Pai may be the best Thai restaurant in the city. I come frequently for lunch and the only complaint would be that the lunch menu is a little bit more limited than dinner. However, everything on the menu is great. The Khao Soi and the Green Curry are my personal two favorites for lunch. The Pad Thai is also spectacular and you can't go wrong with most of their appetizers. They also have a pretty interesting and unique cocktail list and the atmosphere in the restaurant is very lively and fun.
