Fresh Flavors, Friendly Service!
My experience at this restaurant was truly satisfying. The flavors were fresh and the portions were generous, especially with the meat ingredients. The service was friendly, and although it's a little place, it's big in what counts. I definitely recommend it!

Unacceptable Service and Wrong Order
My experience at this restaurant was extremely disappointing due to a significant error in my order and the subsequent poor customer service. I ordered a vegetarian meal of Fry Tofu and Panang Curry with tofu through Uber Eats, but instead, I received beef noodles and chicken pumpkin curry. When I contacted the restaurant about this mistake, an elder gentleman laughed and dismissed my concern, stating they were busy. This behavior is completely unacceptable, especially when dealing with a dietary complaint. They offered no solution to rectify their mistake or showed any understanding of the situation's seriousness. While I did receive a refund from Uber Eats, I wanted to inform the restaurant of the mix-up. However, their response was unprofessional and disrespectful. 👎

Amazing Thai Food, Will Return!
Yesterday, I was looking for some Thai food on the way home and stopped by this lovely spot in a small corner I pass by all the time! The food was so good I came back today! The Chicken Panang, Thai tea, mango sticky rice, and basil chicken were all delicious. The customer service was also great! See you guys again soon, thank you!

Amazing Thai Food and Service!
My experience at this Thai restaurant was amazing. The fried rice was awesome with the beef I ordered. I also enjoyed the fried tofu, which was perfectly crispy on the outside and soft on the inside. The accompanying sauce provided a great balance of flavors. The salad that came with the lunch special was delicious, especially with the unique vinegar dressing. Overall, I was really happy with the place; the food was amazing and the service was great.
