I had the shrimp yellow curry entree. They give a pretty large container of rice with the meal. Taste was good. I like that they put a good number of shrimp in there

Cute place. Good food. Clean. Nice service. Prices are very good. I will be going here for Thai food from now on.

At Diho Siam Thai Restaurant, you can enjoy a variety of Thai and Chinese dishes, which is a great option for those craving both cuisines.

The portions are generous, ensuring you won't leave hungry. I particularly enjoyed their Pad See Ew, although the soy sauce flavor was a bit strong, the overall taste was still pleasing. What's even better is that the prices are affordable, making it a budget-friendly dining choice.
The staff members are also very friendly and welcoming, adding to the positive dining experience.

Overall, Diho Siam Thai Restaurant offers a satisfying dining experience with its ample portions, reasonable prices, and friendly service.

Came here for a weekend late lunch with a group of 6 and it was great. We had to wait 5-10 minutes as a lunch rush died down but it wasn't too bad.

Overall, the portions are quite large and the service is very very friendly and attentive. Just good people :)

We ordered a bunch of things and everything seemed to taste fine but my favorite was the red curry!

I love this little spot. My husband and I have been visiting their various locations for 10+ years. Consistently delicious. We order take out regularly and occasionally dine in. Whenever we dine in, the service is great and the atmosphere is very quiet, clean, and cozy.

Just had lunch at Diho Siam in Lake Forest, and it was spot on! The pad thai was flavorful, and the portions were generous—perfect for a laid-back meal.

The best Thai food in Orange County or even California! This has been our go to spot for a while and will keep coming back. Authentic and affordable

all of a sudden they reduced their dinner menu portion rice to less than a half of what it used to be!!!!! and when i tell them i ordered dinner menu they say yeah, they change the rice portion. unacceptable!!!

I want to thank Nina for making my visit so much better! The food is always great, but in the past, I’ve had some visits where another lady was loud and impatient, making me feel unwelcome. Nina changed that with her warm, friendly, and attentive service. Thanks to her, I’m excited to return for more delicious food!

So far, this is probably the best Chinese food I've had in Orange County. The Pad Thai is also excellent.

Just like some of the reviews say, the lady is rude at the register and service is everything!! Awful attitude and they don’t check orders as often as she should because upon picking up an order that should have been ready, she just put it in to be prepared! Yikes!

Very good Thai and Chinese food. We go often.

Food was good, average type Thai food!
Service should be improved to maintain customers.

Quaint affordable, reasonably priced, good customer service, and fast service, 3 mushroom disj with chicken was good, as well as there fried chicken and beef skewers, good ample free parking.

Ordered from DoorDash. Lousy food. Hot and sour was sweet! Chicken and broccoli insipid. So much for high door dash ratings, AVOID Diho Siam.

food’s so good😭

good food for a decent price; fast and courteous service

Best Thai food around. Always consistently delicious.
Pad Thai
Avocado Mango salad
Pineapple rice
These three are our favorites. Yum!!

One of the server is rude.

This happened after my mom paid using her card in the bill and gave a cash tip:
This server returned the tray with my mom’s card, cash tip and receipt for her to sign but this server acted rude and just slammed the tray on the table.

Note: By % is 10% of total price,

Cute place. Good food. Clean. Nice service. Prices are very good. I will be going here for Thai food from now on.

This place is my favorite since I moved to California. I went there on 9/10/24 around 7pm to place a take out order. The lady at the register was arrogant, disrespectful, very very rude and was laughing at me. Unfortunately my order was not cooked well and tested just like a water. Very bad experience.

Good little place to eat. Lots of menu options and very satisfying.

Just had lunch at Diho Siam in Lake Forest, and it was spot on! The pad thai was flavorful, and the portions were generous—perfect for a laid-back meal.

Leckeres Essen. Wir hatten Pad Thai Chicken und Chow Mein Shrimp, dazu Thai Ice Tea. Alles hat gut geschmeckt. Preise waren moderat.

My family and I have been coming here for over 15 years. It's our favorite spot. The food and the service are excellent and worth the drive from the inland empire.

Good food, Nina provided excellent service. The big negative is a very sticky table all around. Feels soooo dirty. This needs major upkeep and maintenance.

This is our favorite Thai restaurant. It's a nice sit-down place for family gatherings, but honestly pricing is so reasonable that it's even a great place for quick lunches, pick upd or deliveries. Food arrives superfast. Staff has always been super friendly, and great with little kids.

The food is outstanding. Their hot and sour and the egg drop soups are fantastic. Their pad Thai and curries are also amazing. There's satays are fantastic.

We probably go here or deliver at least once a week.

slow stuff

Always fresh and tasty!

I haven’t written a review about a restaurant in probably a couple years but this one I feel needs to be done. I visited this restaurant for lunch today and I ordered the yellow curry chicken dish that was $11. I got water and with the lunch special I was supposed to get a bowl of soup with my meal, the first thing that was delivered to the table was those little crunchy stringy things. Underneath the crunchy little stringy things in the bowl was trash. They were little pieces of plastic that were pulled off of what appears to be a plastic bag then shortly after the waitress came out with a salad, even though I didn’t order salad And she mumbled something under her breath as if she was giving it to me for free. When she brought me my water, there were slimy little specs of what appeared to be boogers on the side of my glass. I gave them the benefit of the doubt and wiped it off, thinking that it was maybe some rice that had smeared onto the glass when they had poured the water in the kitchen. Then my dish came with the soup when I got my bill it was $22 instead of $11. I eat out often and I know that sometimes people make mistakes but this place sucks. I didn’t argue Bill Because I had to leave in a hurry. But I will never eat here again.

This is a gem of a restaurant. It has amazing food, super friendly hosts and very homely atmosphere.
Definitely coming here again.

Amazing food. great lunch specials

Good service and excellent meal.

Nice people but it would have been five star if they had let someone wait on us that spoke English because communicating was extremely difficult and two of our four food items were incorrect

Yellow curry is a must try

Food always excellent, service gets better every year
Atmosphere the same local dining hole. Prices are great

decent selection of Chinese and Thai dishes. good portion sizes, try asking them to tone down the salt tho. pricing is okay ($15 avg a dish) but the value is alright. my usual go to now for Chinese/Thai takeout.

Tasty food. Good portion sizes. I have been to the location in Mission Viejo and I would say it is comparable.
I got the pan-fried noodles with beef over a bed of lettuce. Flavorful sauce and good amount of beef

Had a chicken pad Thai with green salad. Everything was fresh and full of flavor.
Just plain Excellence!

I typically get either red curry or Thai fried rice at least once a week. I enjoy it.

We ordered a bunch of things and everything seemed to taste fine but my favorite was the red curry!

The food is like from Thailand! I can only recommend!

Yellow curry with shrimp, scallops and avocado is amazing

If you enjoy tasteless bland food which appears like Thai dishes, then this is your favorite restaurant. Otherwise search for real Thai food elsewhere...

Gai yang is so dry it's like it's been cooked 3 times, and is bland. Rad na is okay but the chicken in it is super dry.

Must I explain why?

This place has great food and the restaurant is decent looking. It looks clean and organized but it is not anything extraordinary when it comes to ambient. The food however is amazing!!! To me that’s what really counts. People emphasize way too much in service and in other pointless things. What really matters the most is that the food is delicious and this place delivers just that.
Give it a try, you won’t be disappointed.

Great food

Been going here for 20 years. Love the shrimp fried rice but the crying tiger was kind of dry.

There is a very arrogant person in this place, she might be the owner, I think she is not the one to treat customers, she also does it with delivery's

The food was terrible. We spent around $70 and non of the dishes were good, specially the terrible smell and taste of the Kung pao chicken.

Wonderfully flavorful food at a reasonable price! Outdoor seating for their customers' use.

Cancelled of the items without letting me know.

Food over cooked. Added extra meat - they ignored but still charged me.

This place is joke

La comida es rica, los platillos son grandes y para colocarse al centro. Tienen comida china y tailandesa.

One of the employees is extremely rude and treated me really bad, not all of them, just one, but if you care about customer experience, I would not recommend the place.

My all time, consistently great, go to restaurant, is Diho. I have been going here since 1987. The food remains my favorite and the staff is beyond fantastic! Everything on the menu is exceptionally delicious.

Okays food

Sad that I didn’t try this place sooner. Phenomenal Chinese food and great service. I’ll definitely be coming back!

Everyone seems to complain about the old lady, but didn't experience that. But the food was subpar. It wasn't bad, but for a Thai food aspect, no flavor.

My family took me out for a birthday lunch, to Diho Siam the other day, and as usual, food was delicious, and Norma was really nice! Unfortunately, we again ran into this very rude lady, DANG, she is just outright obnoxious, and really difficult to deal with, and RUINS the experience. We will not be returning as long as she works at that location.

Rude stuff

Excelente servicio y muy buena calidad en los alimentos

our family enjoyed the food very much, the lady was patient and nice

They serve Chinese food and Thai food. Good lunch special which included salad and soup but no soup included on weekends. Price and service is good, portions right. The chinese food is good but the thai food is great. The owner is such a sweetheart. She's very nice and made me feel like a family friend. She knew long time customers by name. I will definitely be back.

Diho Siam the best Thai cuisine. The desert is mangos cakes.

Menu is half Chinese and on the flip side, Thai. Friendly staff, ut you better be ready when she comes to take your order! I had Phad Thai and it was delicious. My wife had almond chicken and she said it was excellent. Prices are reasonable and the ambiance is nice.

Nice, considerate and friendly Staff, good pad thai, clean restaurant.

Food was decent but it's much better at other branches then this one

I say......to every one...food ok,,,,...but don't pay w your debit card...yesterday I discovered this DIHO SIAM restaurant is ChargingMy debit card for over a year 21+ time ...and I only went one time in October 2021...now is 08/31/2022....my bank only can pay me last 3 month transaction...I'm a hard working person....working hard for my money..........is over 800+ $$$ from this restaurant ...

Delicious

The service is one of the WORST I have ever experienced in my life. The old short lady that takes the orders should resign & find a new job, terrible for business. She literally smashed our left over food with her hand and through it in the trash can cussing to her self about us.

The worse service ever! The old lady looked like the boss complained in front of the customers that their only one waiter who was also the cashier was off, so she had to take care of everything. She yielded and complained in front of us right after we asked for spicy sauce. Then she avoided us without taking care of us till we had to go to the cashier to pay. We still paid the tips but for sure we will never ever visit again. Nobody wants to see waitress give you attitude even smashed the food with her fingers after she grapped your plate. We felt frightened and didn’t want to experience such a horrible service any more.

We ordered from this restaurant since 2019 and loved everything, but tonight I ordered meals and got chicken instead of pork. Because we ordered through Door Dash and I have no idea how DD handles things, I called directly to speak with the restaurant. The woman on the phone told me her chef insisted it was pork. I told her I was looking at the food and tasting it, and it was not pork. She still insisted very rudely that it was correct. I tried again saying that it’s not a big deal, clearly it’s a mistake, but it’s not correct. She insisted again even more rudely. I repeated it’s just a mistake, but I’m looking at and tasting this food and can assure her it’s not, and please work with me because we have ordered here for a long time, but there are plenty of other Thai restaurants around we can pick from. She told me to go to DD and then hung up on me. I don’t understand the hostility right from the start when I called. I’m sure the chef thinks they did it right, but there are how many orders cooked at a time? Why does the chef’s memory rank over my real-time experience? It was also very oily this time, more than usual.

THIS TEAM MEMBER IS HORRIBLE! She yells at customers and my grandmother. She needs to be told off by the management! She's horrible!! I was about to flip! She's so rude!!!!!!

Tom Kha hot pot is always so tasty and satisfying. The satay was perfect. The veggie delight was nicely seasoned and great. The yellow curry had a touch of heat and was smooth and delicious. The staff is always friendly and when my friend asked them to delay the entrees they did. Not a huge deal but too many restaurants don't or won't or can't. We are regulars and clearly most of their clientele are.

Delicious with Thai and Chinese style
and after course will surprize with Fortune Cookie

Love the crispy duck and curry

Kim that was outside as host on Sat. at 10:30am is simply wonderful...He was very welcoming, friendly, humble, curtious, great knowledge, very helpful...😁

Very good service, prices are not high food is delicious.

Food always delicious here. Recent lunch with my friend we had Beef Salad, Green Curry Chicken and a noodle dish that she ordered. And sat outside on a beautiful SoCal day. 😁👍

I love how authentic and traditional the food is here.
(They even have the 1970s Tom Jones background music 😂👍🏼).

Food here is really tasty and great value! (Esp the chicken satay)

Calm restaurant with tasty Thai and Chinese menus. The hors d'oeuvre plate was filled with crunchy delights that my toddler loved.

Chicken pad thai.
Good food. Could have been a bit more flavorful/spicy
Table was sticky but the ladies working there were nice

Amazing flavors and great good. Friendly staff, would come again!

The lady who owns the place was very rude. Did not get what we asked for like the sauces and more napkins. Wasn't very hard at all either. Food was good, just bad service

Ordered the ginger mushroom trio with tofu and jasmine rice and egg rolls. This was ridiculously good and the togo packing job was excellent. I don't have a single complaint... not too greasy, flavorful, fresh veggies, and even the chicken in my roommate's order was tender and soft. The mushrooms sucked up the garlic flavor in a blissful way. Shop is clean. I'd come every week if I hadn't realized it was there a week before moving!!

Panang curry amongst the best in south oc... Lunch special is def worth it... Salad and salad dressing also very good

I agree with one of the reviewers of this place. The food is good. We have had no issues with that. I could easily rate this place 4 to 5 stars -- but I knocked off 4 stars and giving it a 1-star rate, because for the 3 visits and patronization of this restaurant, my family and I encountered the eldest, short-statured female Thai server twice. For both times, she was RUDE and SARCASTIC! On our first visit, I tried to give her my orders (6 dishes) as I typed it on my phone - for her convenience - I thought I was being nice but it backfired on me! She said she doesn't touch people's phones (I was holding my phone and showing my list of orders to her!) On this particular (#3) visit, I ordered their soup, Tom yum with shrimp. I politely asked her if the shrimp has shells on it (some dishes, especially Asian dishes, do leave the shells on their shrimps). I was expecting a simple yes or no answer which would've been sufficient... Instead, she lectured me in a loud enough voice, that the other customers looked at our table! My mom controlled her temper to not answer her back and I, being younger than the server, just brushed off her rudeness! I didn't order much this time and our bill was $36 and I considered not leaving any tips at all but she hardly served us coz there were 2 other (Latina) servers who catered to us more than she did (and have much better attitude than her), so I thought the tips would be shared with them. It's too surprising to learn that this Thai lady has been serving there for over 30 years even though she clearly doesn't have a good customer service at all! It's time for her to retire!

Very happy with my take-out experience tonight. Had to review. First of all they had real angel wings. Thai restaurants seem to be going away from offering these because they take time to prepare. And they were big and very tasty. Pad Thai was above average and huge portion with lots of peanuts. And the pricing on both of these was very low. I absolutely will back many times. Can't wait to try other items.

Don’t go there

Resturant is good but the staff : particularly one waitress - short and Thai speaking - is super rude. Today we went for lunch and the bill was $60. I paid $70. But to my shocking surprise she throw away the bill book on floor and start speaking very rudely. My wife saw and went back to her and said Excuse me- she said go away I am talking to myself. How could a restaurant keep such a rude aggressive abusive waitress. NEVER GO TO THIS RESTAURANT.

Pad thai, fried rice

I’m a person who enjoys a delicious spicy dinner , and tonight I enjoyed some Thai spicy noodles that made my taste buds fall in love , it was spicy and flavorful but most importantly enjoyable thought the whole dish 👍

Nice little shop; food is authentic and good. Great staff that make you feel right at home. We sat outside and enjoyed our lunch. We will be back soon.

Amazing! Fresh food, excellent service and great flavors-HIGHLY recommend!

Good Pad Thai. Nice people. Good service.

Good Pad Thai. Nice people. Good service.

I came back after 2 years and it’s still the best ... 2021 original 5 star previously... awesome food...

The food was fresh and tasty. We ordered yellow curry and drunken noodles. The curry was to die for. I ordered another one to go. The owner lady was very nice as well.

Love this place! Always great food and service!

Highly recommended, great food

Fantastic food and service. Delicious!

Such friendly service and the food is fresh.

The best Thai food in South Orange County. Always delicious and the service is wonderful. It's my favorite restaurant.

What a hidden gem. Service was excellent & the food we'll the food speaks for its. Prices are very fair, borderline inexpensive. I highly recommend.

Our first visit in 8 years due to a relocation to the PacNW. It was every bit as good as it was 8 years ago. Chicken satay, potstickers, po thak soup and pad thai all freshly prepared, super delicious and plentiful. Haven't been able to find Thai food this enjoyable anywhere in PacNW area. Will surely be back whenever we visit Orange County.

Food is fantastic, love the drunken noodles, pad se ew, and spicy basil. The ladies are great and the outdoor seating is perfect on nice days.

One word AMAZING!!!!!!!

Thai is my favorite food. This is my favorite Thai restaurant. Love every dish and the service is on point and the prices are excellent particularly for the high quality. My dishes are green bean curry, coconut soup, and yang Jim (they call it Tiger something now).yum!

Great food!

Great place for lunch. Excellent dish choices and great service.

Best yellow curry with potatoes and chicken around. The only reason I gave it a 4 is I am no sure the kitchen and bathroom are the cleanest.

Food is good but pickup service is a nightmare during the virus. Thai restaurants are already supposed to be used to pickup but this place is a disaster.
Everyone jammed in a small place. No process for announcing orders. Lots of people with no masks or social distancing.
Avoid until business returns to normal.

Passing thru Irvine and stopped for lunch. This is by far one of the best Thai restaurants I’ve ever been too. Outstanding, friendly service to match the food. Will be stopping here every time I’m heading to San Diego. Thank you ladies for a wonderful lunch

My short review from a out-of-towner point of view is that I recommend Diho Siam. Great Thai at reasonable prices. But like I said, I have no comparison to the area, only to the authentic Thai places that I have in my area in the Mid-West.

Whether I’m in the mood for Thai or Chinese, Diho Siam is my favorite restaurant and their quick service is always predictably delicious!! My favorites are the Hot & Sour and Tom Kha soups and the egg rolls!! Diho Siam never disappoints and always satisfies!

Food is too good

Consistently good food (whether from their Chinese or Thai menu) for a fair price + these ladies hustle and provide good service even during the busy lunch hour. Love the fresh flowers!

Love Diho! I like to order the Tom Kha soup with shrimp, and Avocado curry with shrimp and scallops (green curry, least spicy) and brown rice. Delicious food, friendly servers. Parking can be hard depending on when you go bc its basically a huge food court.

We always enjoy our food and service.

I am glad I found Diho Siam. Everything I have tried is tasty and I haven't been disappointed yet. The staff are friendly, and the place has a family-run vibe that makes me feel welcome. I recommend the pineapple rice, but my favorite is the green curry.

Delicious pork rah nah. The gravy is more on the sweet side, but that's how I like it.

Excellent service and the food was really good. I’ll definitely be back.

Out of tofu? Seriously?!

very very good

The food was dissapointing. The service was very average. The table was set with only forks to eat fried rice and large pieces of fried chicken.

Staff was polite. But that does not compensate for the tasteless food served.

I was surprised to see so many positive reviews.

THAI KITCHEN in Irvine is streets ahead in taste quality and service.

The owner at Diho Siam always has a smile on her face and really cares about all the people who enter her restaurant! The is also amazing!

Amazing Tai/Chinese cuisine
Fancy atmosphere, affordable, delicious food.
Recommend house specialty chicken, & avocado mango salad😋

This place have great food and great prices!!
Thank you

Clean, nice atmosphere, attentive staff and delicious food! Specialty Chicken (new year chicken) and Pumpkin Curry were soooo good! Will definitely eat here again.

Great food

Meah. Nothing to write home about, just the average Chinese/Thai place.

Love it there

Fantastic Curry! Brown rice awesome too!!!

I like that they serve Thai and Chinese food. The portions are generous and delicious. Beat the lunch crowd or go for dinner to enjoy your experience. The staff is very friendly.

I live about 30miles away from Diho Siam. It is definitely worth the drive because I always have a wonderful experience. I have had multiple visits and every single time I go, the employees always seem to know some of the customers. It's a combination of the delicious dishes and magnetic personalities of the staff that keeps bringing customers back. I have never waited more than ten to fifteen minutes to receive my entrees. The only drawback is the parking situation of the plaza, but if you can avoid the lunch rush, you'll have no issues. This humble restaurant gives me a sense of nostalgia. The spicy vinegar with chopped peppers brings me back to my childhood, when I would create spicy sauces to match each meal. When I walk into the establishment, I'm transported to a memory where my relatives invite me to their kitchen to feed me. If you have never been here, give it a try. I want to know if anyone else feels safe and at home here, like I do.

The Pad Thai was super yummy, I asked for it very wet and it was extra sweet for that reason, just the way I like it. I also ordered a red curry with pumpkin that was pretty delicious too.

I've been a loyal customer far too long and they know me since I typically order 'New Year Chicken' to go. Great food but good luck finding parking during dinner time and weekends.

The food is so flavorful

Always superior food and service. Go there often never disappointed.

So impressed with the delicious food and the service was wonderful!

Drunken noodles were rad 😊
