I love this place. I've never had a bad meal here. Make sure to make reservations. Perhaps the only way you can walk in without one is if you go for dinner at 5pm.
We always get the grabong (squash fritters, $12.50) to start, and always wish we'd ordered one for each person. The garlic tamarind dip is magic. It's stupidly good. I often get the gaeng masaman with braised beef ($15), as well. I ask for it mild, and I inhale the whole thing far too fast.
The Gaeng Kiaw Wan (served in a coconut, $18) is also really good. You choose the meat you want in the green curry, and you eat it from a coconut. Come on, why are you still reading this? Just go to Pai already.
