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!

Needed a quick dine in for a short lunch, one person. I told the servers and they accommodated my request.
Meal and tea was served quickly and tasted great. There was no waiting for the bill.
I’d say I was in and out in less than 20 minutes.

We absolutely loved our dinner here! The vegan yellow curry is the best curry I have ever had. The seasoning and creaminess were just right! Service was wonderful too. Highly recommend!

Really delicious and tasty food here. The yellow curry Chicken is pretty flavorful and the combination fried rice is great with the jalapeño vinegar. So much rich tate when mixing the food together. The service is also very friendly and attentive to your needs. The BBQ chicken and ribs are popular dishes.

Thai Diamond BBQ is one of several Thai restaurants in the area. However, this restaurant serves entrées that closely follow authentic Thai recipes from central Thai land. You will enjoy menu selections not found at other restaurants. Food items are served promptly and very hot. The entrée presentation is only second to the delicious taste. Service is courteous and professional. The ambiance in the restaurant is very inviting. The price point is at the market price for the area.

I’ve been coming here for over 10 years and the food has always been consistent and delicious and they always have impeccable service. This definitely the best Thai food in the IE. We come here at least twice a month. Get the Panang curry and pad Thai

Great restaurant! I ate their Rad Na with Soy Shrimp and I had an excellent time! I was surprised and excited that they even had the option of vegan shrimp because I am allergic and have never had the opportunity to enjoy the flavor of shrimp.
Also!! Their Thai Tea Lemonade had a very intriguing flavor!
