Khao San is my favorite thai food restaurant. They do everything right from friendly service to great atmosphere to presentation to outstanding food. I eat thai food all the time, and this place is on top. Commonly my favorite dish is the red curry. It is the best in town by a mile. Watch out though, three star spicy is crazy spicy. Make a reservation because the restaurant is quite popular and has very limited seating. They commonly turn guests away due to not being able to fit people in.
