I thoroughly enjoyed my lunch experience here. I ordered the chicken curry, which was absolutely delicious, while my husband opted for the beef green curry. We’ll definitely be returning!

Really delicious and tasty food here. The yellow curry chicken is pretty flavorful and the combination fried rice is great with the jalapeño vinegar. The service is also very friendly and attentive.

My wife and kids love this place. I've been coming here for 17 years. It's the best Thai restaurant in the San Bernardino and Riverside area hands down. I definitely recommend this place.
