As everyone has mentioned, this place is fantastic! My wife and I went here for a dinner and the food was great. We had tum yum gong which was amazing, though a bit spicy (we ended up ordering one medium and one plain and mixing them).
The mackerel with spicy sauce was excellent and the mango salad a bit too spicy for us but delicious.
There was no one in the restaurant but they still called in a guitar player so we could have some live music while we ate. None of the waiters spoke much english and the owner wasn't around so we never met them. Was looking forward to chatting with her after reading the reviews. Great place and we'll be back!
