Diho Siam

This is a nice small mom and pop place that we frequent quite often. The service is fast and efficient. I would also recommend that you go to this place for take out. I really enjoy the almond chicken dish. I recommend that everyone gives this place a try.

I have enjoyed their food over the years, but what I found in the coconut soup this time around, has me rethinking. I’ll try to post a pic.
Update-​I just spoke to someone at the restaurant and they were very apologetic and will keep and eye out so it does not happen again. They are very interested in making sure all is ok with the food that they serve so I am happy they are going to address this moving forward.

We have been here several times. They have the best Thai food in OC. We’re just love Sara, she takes great care of us. love the food. Highly recommend this place.

This Thai /​Chinese Restaurant used to be our favorite «go to» when we were in the area. My husband and I had dinner last week and the quality of the food has plummeted. The service was terrible. The restaurant was only half full and they did not say hello when we entered or when the «hostess» seated us. I thanked her for seating us and thanked her again when she brought us water and she just spun around and went into the kitchen without a word. Bad attitude and bad food = never again. There are too many great choices for Thai food out there. Don’t bother eating here!

This is a small, but rare gem in Mission Viejo! They have Thai and Chinese food and it is fantastic! The servers are warm, friendly and bring out delicious and fresh food. I love how you can make a «mini combo» with yummy soup (I love their won-​ton!), an egg roll and these amazing potato-​curry dumplings.
Go and try it and you will love it, too! :-)

I’ve been coming here for years and the quality and service are always amazing. I have never had a bad dish here. I will say I enjoy the Thai side of the menu better than the chinese. I love the noodle soup with chicken and the raad na. The salad dressings are amazing and I regularly come to pick up a 3oz. size of their spicy lime dressing.

Food was delicious, service was terrible. 4 stars for the food.

Tried this place out for the first time Friday night of last week… around 6pm.
There were no empty tables, and we stood in the doorway for a few minutes, then walked up to the window towards the back and asked if there was somewhere we give our name. Turns out there was a small book near the front door to sign in on. There is a small bench near the front door to sit, but other than that, there is no extra room in this restaurant. Its very small and very awkward if there is anyone waiting for a table.
We only waited maybe 5 – 10 minutes and were seated. The tables are close together, and again, the place is pretty small, and it was WARM! We were just outside the entrance to the kitchen so maybe it was warmer where we were. They do have ceiling fans, however they were not on. I will say, I noticed they were filthy. Someone propped the door open at one point, and that felt great, but someone else quickly got up and closed it.
I have been craving a coconut thai soup for, at this point, I would say months. Not sure the name of it, but I wanted it. I have had it at a Thai restaurant I go to sometimes for lunch, but its just the soup of the day with their lunch specials sometimes. So, I ordered the Tom Kha Hot and Sour Coconut Soup here, and YES! It was the best! It was more than I expected and just what I was craving and I was so happy! We shared an appetizer of eggrolls and those were really delicious as well. The eggrolls were so hot it took a while to eat them, and the soup as well. Everything was steamy hot and so fresh.
For my entrée I had the Pad Se-​Iew. It actually was almost too hot to enjoy, but was still good. Food being too hot, is not a complaint. The leftovers, that I ate cold, were also really good.
I will definitely be back here again! Especially for a big fat order of that soup!

This location would have 5 stars if it weren’t for the kitchen staff. the floor employees are awesome. Servers are always super sweet and accomidating. Unfortunately, the chefs aren’t equally up to par. Aside from each dish tasting incredible, I had one aweful experience I can not forget.
I ordered the pineapple curry for dinner one night with tofu since I am vegan. I have ordered this dish before and it is always incredible. Once the food arrived, the tofu had magically came out as chicken. I’m vegan. I do not want to see a bowl of chicken curry in front of me. The waitress realized the mistake before even setting the plate down and she gave me an extremely sincere apology explaining that the kitchen screwed it up and she knew I ordered tofu.
Alright, no problem. That’s totally cool. 5 minutes later I got a new bowl of curry. How can a new dish be completely remade in 5 minutes? It can’t. Luckily I saw chicken chunks throughout the TOFU curry before taking a bite. Once again I called the waitress, explained my predicament, and she apologized once more before running the plate back to the kitchen again
Finally, 45 minutes later once my entire family was done eating, my curry arrived. I didn’t eat that night, boxed my food up, and went home.
Its too and this experience happened because I have a deep love for this restaraunt and the waiters are always aweosme.

Great thai food!
The soups are really good, and the Fresh Rolls are amazing, too!
There is always a good sized dinner crowd, so be prepared to wait a little bit. But I’ve usually ordered takeout and it is quick and reliable. Never had any issues.

Best Thai food In mission Viejo. Service is great sometimes they get really busy and it takes a little it of time to order. My favorites picks are: Thai shrimp avocado salad, pad se eww, Panang curry, glass noodle soup and the coconut rice with mangos for dessert. I would highly recommend! Everything is delicious, you can also order authentic Chinese food too!

My wife picked up some thai food on the way home this past Sunday from Diho Siam. This was the first time trying this Thai place since we had just moved into the area. We ended up getting the Tom Kha (Hot Pot) and the Crying Tiger.
I will start with the Tom Kha. Now I know that every Thai place has a different take on the Tom Kha which is to be expected. This was perhaps the worst Tom Kha I had ever tried. It was very watered down and was lacking veggies in it. Maybe I should of looked at the ingrediants but all it had was chopped up mushrooms (which were not many) and some pieces of chicken in it. The broth was so watered down that it literally felt like I was spooning out water and it really didnt have any coconut flavor to it.
The crying tiger was okay. The meat had a good flavor and it came with two different sauces to try with it. My only issue with this was the two giant stripes of fat they put with it. Do they really expect someone to eat the grissle. No, I am not John Candy in the Great Outdoors trying to polish off a 72 ounce steak to get it for free.
Overall I have experianced a lot better thai food. And the prices were definitely overpriced for the two items I received. I will probably try this place again hoping it is better but I wouldnt seek this place out if you are looking for a good Thai place in Mission Viejo.
Cheers

The food is great, the prices are reasonable but the service can be slow at times… Definitely worth a try!

PLEASE READ– WARNING BAD SERVICE AND THEY WILL CHASE YOU TO YOUR CAR!!!
Ok– so my husband and I have ordered from this place in the past (approximately 2 – 3 times) but they have always been pick-​up since we have two children and sometimes it’s just easier to eat at home. In the past, we’ve ordered their pad-​tai and pad-​see-​ew noodles. Those two dishes have been pretty good-​not the best I’ve ever had but good enough to take the craving out of the way.
So today, being that we had plans to go somewhere after our lunch– my family and I decided to go and actually eat at the restaurant. The place is small but we were one of three tables, so the place wasn’t crowded. We ordered and that’s when the chaos began! First of our waitress (thin built-​long hair) was nice but after taking our order and bringing us some of our food, she never once came back to check up on us– my husband kept having to waive her down. There was another waitress (a little heavier set– short boy cut hair) who was also in the restaurant.
This second waitress came and dropped off some of our food and practically slammed the plate down at our table with attitude. We didn’t think anything of it– nor did we complain, we just proceeded to eat our food. However, at one point my husband waived the second waitress down to ask for something or if she could get our waitress– the second waitress looked straight at my husband, made eye contact and continued to walk towards the kitchen area. We assumed she would get our waitress but our waitress never came– again we continued eating and didn’t say anything.
At this point, we just wanted to eat and get on with our day. While eating, I accidentally tipped my cup with my elbow and spilled my ice tea on the floor. There was broken glass everywhere and ice tea underneath our table– surely we thought they heard and would come out to see what happened– NOPE!!! Neither of the two waitress came out to the dinning area to see what happened. I mean for crying out loud– it was a glass cup and it was loud!!! When we FINALLY were able to waive our waitress to our table once again, we advised her about the broken glass and ice tea under our table– surely she would offer us another table– NOPE!!! She told me to leave the glass there, move aside as best as I could and just brought out another ice tea!!! ARE YOU KIDDING ME??? I was super upset!!! How do you not offer to move us to another table so that you can clean up the glass? There were plenty of tables for us to move to. At this point– my husband decided to ask for the check– I couldn’t eat anymore, I was very upset and bleeding from my foot.
Before bringing us our check the second waitress told us our dessert was on it’s way out. We advised her that we would take it to go– since I didn’t feel like being there anymore and needed a band aide to stop the bleeding. We decided to pay for our tab but agreed we wouldn’t tip. My family and I eat our at least once a week– we alway tip– we understand people need their tips and rightfully earn them. However, I will not tip for bad service. I don’t feel someone should be given an incentive they didn’t rightfully earn. Why would I tip you for being rude, having to waive you down multiple times and making my family eat with glass underneath our table? We signed out check and walked out– you would think that would have been the end right? WRONG
As we were driving away, our waitress followed us to our vehicle and asked us why we didn’t tip. We nicely told her the reasons and she proceeded to nod her head and said «Ok.» Well to make matters worse, my husband forgot his set of keys at the table (since we left in such a rush) he went back to the restaurant and what happened next you wouldn’t believe. The second waitress decided she was going to argue with my husband about not leaving a tip (remember she wasn’t even our waitress). Once again, he explained the reason and she continued to argue with him, while other costumers were sitting down eating. Please tell me where is their professionalism? Why would you argue with a customer in front of others? After a few words were exchanged, my husband grabbed his keys that were behind the counter and turned to walk outside. The waitress followed behind him, yelling at him and saying things to him in another language until he got back in the car.
This is seriously outrageous!!! Why would anyone argue with a customer like that? Why would you do it in front of other customers? If you care about your business and the service you provide, you wouldn’t go down to this level of argument. I come from a family that owns a business and I know this is not how you would handle an issue with a customer.
Of course it goes without saying that my family and I will NEVER– NEVER– NEVER come back to this restaurant again. PLEASE PLEASE save yourself the DRAMA AND HORRIBLE SERVICE and go somewhere else to eat!

When my sister was a student at Soka University, this was one of her go-​to places. She recommended this to my parents and they loved it. Finally, I’ve had the chance to try out the food here after a family outing in the area.
Service here was great! We went around 2 pm on a Sunday and it wasn’t packed. Our party of 6 was immediately seated and first round of drink orders came promptly. Food came out quickly as well.
My sister got the Thai iced tea and I was surprised that it wasn’t too sweet like many Thai places. I wish I ordered it for myself! As for food, I ordered yellow curry with pork. My mom and my sister ordered pad thai and fried rice so I got a chance to try a little of those too. Delicious!
I live out in Torrance so it’s a commute, but if I roam in the area again, I will surely visit!

I ordered food for pickup and arrived 20 minutes early. They were incredibly accommodating and I only had to wait 5 minutes for my food to be ready. Everything was delicious and large portions. I will definitely be coming back. Thank you for a great evening!

Nice employees, BUT food was not the same taste or quality, PLUS I found a metal twist tie in my Tom Kha soup which had a strange orangish tint to it. NOT going back. Please see in photos

My husband and I went here around 4pm, the place was empty though we noticed a lot came for take-​outs. The staff are friendly. The food is superb! Authentic thai food! We ordered the pineapple curry which is the bomb! and the crying tiger (bbq beef), both comes with rice. They are a little pricey compared to other thai restaurants but we’re definitely coming back.

We ordered pick up from here not too long ago. My Mom didn’t want to cook dinner so I ordered some Thai food over the phone. The lady on the phone was nice, a little hard to understand her with her accent, but she got our order right and it took a reasonable amount of time for our food to be ready. We got their cream cheese wontons, Thai beef salad, shrimp and scallop avocado yellow curry and beef fried rice.
Lets start with the good part. The wontons were yummy, crispy, crunchy with a creamy filling and a sweet sauce that balanced the rich dish. The salad had a generous amount of beef on it with great dressing. Next the bad, their shrimp and scallop avocado yellow curry has always been mine and my Mom’s favorite, but this time the scallops were like rubber balls. Bouncy and chewy, bleh. The shrimp was ok and the avocado was amazing, creamy and rich. I’m normally not a big avocado person but I would eat a whole avocado if it was prepared in this curry. It’s just the scallops were bad and there were a lot of scallops in the curry. The fried rice was greasy as usual. A couple days later after this meal we also ordered their chicken Tom Kah Gah (coconut soup) for lunch and the chicken was super dry, the soup didn’t even help it. I just ended up slurping up the soup and putting the chicken aside. I’m sad this places food isn’t exactly as good as it used to be.

This is one Small but Great restaurant, Good Food– Both Thai & Chinese
Great Service– We will continue going there
This is the one on La Paz in Mission Viejo
