I’ve been to hundreds of Thai restaurants over the years, and this one was below average. Several dishes lacked authentic flavor. I was just visiting and chose it based on reviews—surprised to see it's rated as the best in the area.

The Mango Sticky Rice was the cherry on top of a fantastic meal.
The service was impeccable; our server was attentive and knowledgeable, making great recommendations that truly enhanced our meal. Overall, this place offered a wonderful dining experience that I can’t wait to relive. Highly recommend it to anyone looking for great food and a lovely atmosphere! I’ll definitely be back! 🍽️✨

Very good Thai food here. Service time is reasonable, waiting for food is not long. Price is fair, maybe on the higher end but worth it. Just check your bill at the end cause gratuity is included already, for bigger groups.

My go to place for Thai food! Never been disappointed here, and I love Thai food 😋

We like going here. Best Thai food in Rancho. Great prices. Great portions. Great service.

Food is delicious! Good service. I drive almost an hour just to come here and eat. I have always enjoyed eating at Thai Diamond Bar B.Q.

Everything is ok except the shrimp. Either it's overcooked or they're serving old shrimp. It is sometimes mushy

Real good Thai dish like in Thailand food

I thoroughly enjoyed my lunch experience here. The restaurant offers lunch specials featuring half-sized portions of their regular menu items, which was perfect for me since I often end up with leftovers from full portions. I ordered the chicken curry, which was absolutely delicious, while my husband opted for the beef green curry. We also shared a calamari appetizer, and every dish was flavorful and satisfying. The service was excellent, and the restaurant was clean and well-maintained. I recommend this place, and we’ll definitely be returning!

Nice, clean establishment. Our party of 8 got seated right away and we were quickly greeted by the waitress who then took our drink orders. Good selection of imported beers. The food came out quickly and undoubtedly fresh.

Their restaurant was our first choice because of their menu options for Vegans and Carnivores to dine together. Another big plus was the fact that they stayed open a bit later than other comparable restaurants in the area.

Whenever we are in the Rancho area, this is our Thai restaurant. Great service and food !

Food is excellent.
