I came here for dinner a little while ago, there was about a half hour wait...less than at Khao San Road. The food was definitely worth it! I had a golden curry and it was really good. Service was decent. Will be back. :)
Edit: I've probably been here another 10 times since, it's definitely my favourite Thai place in the downtown core! Green curry is cute, served in a coconut and very flavourful. Pad thai is excellent. Thai tea tastes exactly what it should taste like.
