One of the best Thai foods I have ever had. The service was fast. The lunch portion was huge considering the price and it came with the most delicious sour and spicy soup. Can’t wait to go back

Absolutely Delicious. Great Menu. Has things for everyone. Great value for what you get. This is my go to place to bring dinner for mixed aged family group. I let them do the cooking. Everything has been delicious. I’m crazy about their Green Papaya salad. So few places have it.

Visited this place earlier this week with my family for dinner. The place was packed and was very lively.

The service initially was a bit slow but once we placed the order, the food came pretty quick. We ordered fried rice and massaman curry and both were really delicious.

The staff was not super friendly and there is room for improvement in this area.

The restaurant has a good ambience and a really good variety of dishes to choose from. The curry portion was good enough for one person, but then the fried rice portion was huge and easily two people could eat.

Ample parking available as they are located in a mall. Will surely visit again.

Joe and his team go above and beyond. Amazing Thai cuisine and they treat their guests as family. Our kids are grown now and they still want to take friends to Diho when visiting. Love their personal touches and connection. Their Pad See Ew with extra veggies will change your life. Thanks for being reliable and authentic. Cheers.

What a fantastic restaurant! We had three lunch specials that were a phenomenal value and extremely tasty. Waiter even brought us our food to the public seating area. Couldn’t be happier!

New favorite thai place in the area! Husband and I just moved and were looking for a new thai place. We ordered the pad thai, yellow curry, and cream cheese wontons. Everything was exceptional, flavoring was great, huge portions (we both ate this for 2 meals), and we'll be coming here regularly.

I moved to Colorado 2 years ago and have been missing the chicken fried rice! I visited this weekend and had to stop in. It was as delicious as ever!

We take out here every couple weeks. The food is always great and ready right on time. We’ve tried about half the menu and every dish has been great. Love it!

We were denied dine in service as they were closing in 30 min. Person who took our order didn't seem interested in our business. Gentleman who brought thr food out was super nice and amazing. Food def gets a solid 5 stars

Best Thai in OC
Yellow chicken Curry

I know it's not Thai but soooo good

Good food, nice staff, wasn't too loud inside, will come back

The Tom Kha soup is excellent, so is the Yellow Curry. The beef satay is flavorful, but the meat was a little tougher than I would like.

It was 8:25, they close at 9. The two workers looked at each other and at us and said nothing. I said hello and we were sat. Then told to order right away and be done eating by 9 or take to go.

We left.

My favorite Thai restaurant! Their food is so fresh and great quality. I highly recommend.

Excellent food and service lots of gluten free products

The food is absolutely amazing. I have been going to Diho Siam for many years and it has always been 10/10. Thank you guys!

I've been going here for 13 years
The quality of food and service has never taken a dip in that time.
As long as they are around they will always be a staple in my culinary Rolodex -

Crying Tiger and M Curry was fresh and delicious. Great service.

They are so nice here they gave me flowers to take home! The food is also so yummy

Love the yellow curry

Great dinner, we had wonderful steamed potstickers and other dishes.

Inside looks like a typical strip mall Chinese / Thai Restaurant. Servers aren't particularly friendly but they are fast and proficient. The food is surprisingly great. My personal favorite is the fried shrimp appetizer. Super crunchy outside and perfectly succulent inside.

My favorite Asian restaurant in all of OC. Excellent food with a variety of dishes.
Room for improvement - the phone does not stop ringing during the sitting time in the restaurant, very disturbing.

Best Chinese and Thai food in town!

I don’t ever leave reviews but I need to leave a review for these guys, by far the best Thai food in oc not even close. Great people too

Best food in town

We are regulars there. Their service is exemplary, food is excellent food and conveniently located. .

Nice place, very good food, prompt service!
Highly recommend!

Excellent Thai food. I’ve tried tons of Thai food spots in Orange County and this is one to the favorites. Must try

Best Thai food in Orange County.

Great food and service.

So far, this is the best Chinese food I've had while in Southern California.

Always excellent

TOO MUCH MSG and SUGAR IN THERE FOOD DON'T USE ENOUGH GARLIC AND ONION IN THERE DISHES.

Delicious food and great service!

Good food. Service could be a little better.

Great Thai food, fast service. Lived it

This place is so great. Its comfort food to me. The lunch combos are set at a reasonable cost. If you have been, check it out.

Bomb af !! Definitely coming back

Food is always hot and delicious. Always full and content. The staff is friendly and welcoming always happy 😊

Best noodles in town!!!

Great food at a great price

They always have great food, highly recommend the Pad Woon Sen (Glass Noodles) and the Yellow Curry, those are two of our favorites.

My rice noodles are literally white because of how little seasoning they put in my pad thai dish, I’m a regular at diho siam mission viejo location and i’ve gone to this location twice and both times the pad thai has been terrible compared to the mission location. I’m fed up I can’t believe I paid 14.28 for this 😤

The food is 4 or 5 stars but the service is 1 or 2 stars so they get 3 stars because they are always understaffed. If it says 30 minutes to pick up your food on Friday, Saturday or Sunday double that to at least an hour. DiHo hire more staff!!!!

Ordered for take out and it was great! Place looked clean and good customer service. Will be back

Awful. Pad Thai was mush. Thai Basil Beef was terrible quality. Summer roles half rice?? Thai food has been my fav for 35 years. Probably worst Thai I’ve ever had. Fellow customers need to know.

Kung Pao is EXCELLENT!

Pad see ew

Very nice surprise. I had the cashew chicken. Rich flavors and the presentation was excellent.

Good food with a decent price. Try lunch menu!

Had dinner with family as usual but realized that prices increased around 28%
Come on, inflation is not that high, ridiculous!
Doesn’t deserve the money any more, they lost my family as customer

Great people, good food, good variety. My favorites are the egg rolls, beef satay, and drunken noodles.

Both the Thai and Chinese food taste authentic and they offer excellent service at a reasonable price.

Good food and service!

Great family Thai Restaurant. Dishes are really tasty and prices are very reasonable

This is our favorite thai place!! They have amazing food and the staff is always friendly! This is definitely one of our top favorite restaurants to eat at as a family. We love all of their dishes, especially the spicy noodles, chicken yellow curry, chicken pad thai & chicken thai fried rice. You really can’t go wrong!

Our family loves coming here for lunch, they have special lunch price and the servings are alot. Beef Satay and Pad Thai are our favorite. Salad is soo good too.

I love this place ! I come here probably once a week and place an order by phone and it’s ready as soon as I go to pick up. The orange chicken is AMAZING. it’s by far my favorite place to get it. The guys who work here are so nice and so friendly, I definitely consider this one of my favorite to-go stops especially after a long day at work.

Highly recommend the green curry spicy

This place is like a Kardashian, popular just because it's poplar. Food is on par with the average Chinese buffet, service is terrible, and prepare to wait 2-3 times longer than they tell you.
Simply not worth it.

Excelente

Pad kee mao is fantastic.

Sooooo good, great food, great service. I love eating there.

Great food! Service is great! Super friendly staff! Prices are reasonable compared to other Thai restaurants

Food is great and a big selection to choose from. However I wouldn’t recommend ordering online or by phone call on Friday and maybe Saturday nights as there will be a very long wait and will probably have to wait a half hour to an hour after the scheduled pick up time. During the the week days service is great and you should have no issues with take out.

I’ve always enjoyed eating here and always order their House Special Chicken (New Year Chicken) - it’s crispy and sweet, and just outright delicious. The staff here are outstandingly nice and professional - thank you guys for your food service!

Really delicious food 😋

Been going here for years. Joe is so nice. I don't live in Mission Viejo anymore, but anytime I'm in town I make sure to get some awesome Thai food 😋

This place is great, I used to go there all the time when I lived in Ladera Ranch...

We've been going here for years and they have never failed to provide the best Thai food. We've been to many Thai restaurants in our travels and Diho is always the one we rate the others against. I highly recommend Diho Siam.

They have the best fried rice here. The staff is super friendly and the food comes out quick

Tried all 3 curry dishes and red is a favorite but yellow and green are great too.

Had good Thai food. Good service.

Good food and service

I had the Kung Pao, it was delicous, with roasted peanuts and crunchy little cubicles of zuchiny, or some other goodness.

So tasty, so great, and so differnet from loads of overrated places.

And the owner: the kindest man of all.

This guy who is serving food is a liar we had to wait 49 min just to get 1 item he told us to wait 10 min

Oh my, that Pad Thai!! The drunken noodles and wings are good also. I haven't tried the entire menu yet, but I'm working on it!!

Best food around, hands down of you like Thai and Chinese food. Never been disappointed!

We LOVE Diho Siam. We frequent both locations near our house (crown Valley and La Paz). Never have we been disappointed. I am picky about my Thai food and this is it. If you are looking for GOOD (meaning exactly awesome) Thai food try this place and you will have to stop looking! ;) friendly ppl and good food!!

Had a really nice Sunday eve meal. The portions are generous and the food was very delicious, and our server, Dang, was very nice and attentive.

My friends and I had a rather exhausting day and as we were searching for places to eat, we stumbled upon Diho Siam. We were greeted by a wonderful man named Noi. After we ordered our food for takeout, he had noticed that we didn’t have an utensils or water. He kindly walked to where we were eating and brought us everything we could possibly need; appetizers, utensils, water, and some fortune cookies for dessert. Even as we started eating, he came two times to check on us to make sure we were having a pleasant evening. I would definitely recommend this restaurant solely based on customer service, however the food here was simply exquisite. This was some of the best Thai food I have ever had. A stressful day turned into a still and blissful evening.

Pumpkin curry is as good as it gets! And I’ve had a lot of great Thai food!

Great place to get Thai Chinese food. They have a good selection and their food is always hot and very fresh tasting. My wife loves this Diho Siam and when ever we go to the Albertsons market my wife wants to stop and get take out from this Diho Siam. We have never had a bad experience here. I would highly recommend this restaurant to my friends

Best Kung Pao Chicken in South Orange County, hands down. They also have Thai food. But I’m addicted to the Kung Pao!

Big serving of their food. And it taste good.

I really like the masaman curry and the yellow curry. Both excellent. It’s hard to find good masaman curry so I have grown to really appreciate this place!

This place is really good, and he people that works there, or own the place, are really nice

Service was friendly. Food was quick. Huge portions! Lots of sauce for the togo order. Fantastic shrimp wontons. Everything was above average. Will definitely be back. Thank guys!

This place used to be great. Unfortunately the quality had dropped. I ordered the usual bbq chicken and they gave it to me boiled with a little sear. The meat was way over cooked/dry.

Excellent food and more so the service was expedient, efficient, and phenomenal. Would highly recommend without reservation.

Me and my wife enjoy coming here for a great meal and gear service after a awesome meal save room for mango and sweet rice it really hits the spot

Service was great, food could have been good not so sure. It came out quickly but then again were were the only ones in the restaurant
I lost my appetite when my arm touched the table, tables were sticky, maybe the varnish coming of from the table or years of oily residue
The Water Glasses were yucky, they were all scratched up from 100s of years of service and had a white calcium build up that you notice when the glass dries up

Yummy

Delicious food, good prices, and good service

Food poisoning. 😑

My favorite place for Thai food in ladera/ mission viejo

Excellente, I ate deliciously, great service, yummy yummy. Recomended!!!

Reeeeaaaaally liked this place. The food was amazing! I will go back who knows when but, will def be back. I had the pumpkin curry with shrimp. I still crave it.

Extremely kind an fast service

Always great.

Good thai

Food is tasty and consistent. For takeout, even when busy the staff manage you through quickly to collect your items (Joe is especially excellent). If dining in, the coconut mango rice is a surprisingly wonderful treat for dessert!

What a great experience!!
It was not pleasant circumstance that brought us in for dinner, we walked out of Selma’s next door for incredibly poor service. Even though they were closing in 30mins, Diho Siame warmly welcomed us in, gave us beverages without even having to wait or ask and then cranked out amazing food! Everything was FRESH and flavorful, we had the house chicken and crying tiger, both exceeding our expectations.
This business deserves your money (not Selma’s!) you will not be disappointed!

I wanted to love this place, really I did. I was so excited to see the good reviews... i'm desperate for good chinese food near me, but man does it lack. Tried twice and been disappointed both times. The wife seems to like the curry which I got to go...but the bbq pork was truly awful. As in go home to brush my teeth to get the taste out of my mouth awful. Service is poor. Had to flag down servers for literally every interaction, i.e. ready to order, needing water, tired of sitting there for 10 minutes with an entree I didn't even want to eat and just wanted my check so I can leave. They don't seem to care either. Server asked if I wanted a to go container and I told her no, I didn't enjoy the entree. I got an "ok" and she walked away. Not, "could I get you something else" or even an "i'm sorry you didn't enjoy you meal". Stellar service, truly fantastic. Wasn't even all that busy so no real excuse there.

I asked for extra peanuts in my Pad Thai... Got 0

Recently moved to Las Flores and this has become a weekly staple for our house. Wether taking out or dining in, this place always delivers delicious food. Out favorites are the Chicken Pad Thai, BBQ Pork Fried Rice, and the Orange Chicken. Great staff too, very friendly band hospitable. Thank you!

Stopped for Sunday lunch, Pad Kee Mow, Tod Mun, Twice Cooked Pork. Very good, needed to insist to get spicy, but got a nice Thai chili favor.

If you like Thai and Chinese food... just go! I normally get their fried rice (extra hot) with seafood combination. It's total comfort food and very reasonably priced.

Food is great, however terrible service

Great food. Vegan options. Great service.

Ordered the Moo Goo Gai Pan. Delivery was quick. Not happy with the food quality or customer service. First, they messed up the order and did not offer to correct it. I spoke with Joe. Second, the bok choy was a solid piece of vegetable. It was not cut or prepared in the least bit. The food was also bland. It tasted as if all they added was a bit of salt and thickener for the broth. To top it off, they forgot my chopsticks in the delivery order.

Slooooooooooow AF. bring some news paper or something to read because you're going to spend 45 minutes waiting for you food

The staff here knows my husband and I and knows our order. They are friendly and hard working and their food is soooo good. I highly suggest the pan friend chicken rice noodles and the mango with sticky rice.

Excellent Thai food. My family has been eating at Diho Siam for over a decade and the service is great.

Love it

great food

Truly delicious, we absolutely love this place! Our four year old asks for the pad see ewe with beef regularly. Amazing flavor, and great service!

Best catfish I've had in about 16 years. Delcious. Staff are awesome

Good food and nice service

I can't wait to go back again! We love thai food and found this place on Google maps. Happy we found a new great restaurant to go. The food was great, price is right on and the staff was friendly. Our server volunteered to wash off my son's pacifier when it fell on the floor, so I didnt need to get up.

Diho Siam is great. Great Yellow Curry. Great egg rolls. Best Thai in the area for SURE!

Was seated and waited 20 minutes for water, then to order. The tables were less than half full.

The soup was not hot. The bamboo in it was too fibrous and I could not chew it. It was semi-hard.

The service was okay. The atmosphere was loud and echo-y

Good food but when you’re told time and time again that your order will be 30 minutes to pick up and you get here in 30 minutes only to be told to wait another 30 minutes it’s frustrating. Will be finding a new Thai restaurant because this is ridiculous and food is not so good that it warrants long waits like this. Btw here now again waiting an hour fir take out and there are 2 people sitting in restaurant. :(

Great food and great service make for an enjoyable experience every time I dine in. The staff is always very friendly and the restaurant is always clean. Thanks!

Great service. Internet orders are always easy and accurate.

This place has absolutely fabulous Thai food. The Phase Thai is to die for. The atmosphere isn't much to speak of, being located in a strip mall, but the food more than messages up for it. There is almost never a wait for a table and the process are very reasonable considering the excellent food quality. Highly recommended!

Great food and price.
