I've been here twice and the food was excellent. However, I don't have a lot of Thai experience so I am not sure if this is the best Thai food or the worst Thai food, but it was the best I have ever had.
When ordering they ask you for you spice/heat level with 1 being mild and 10 being hot. I've order at the higher end but didn't seem like ti was unbearably hot or spicy. I have heard though that the number varies based on the cook, so your experience may differ.
