This welcome addition to Dupont Circle is a thrilling adventure in Thai cuisine. There are no reservations, no phone number, and no menu.  It opens at 5:30 but many patrons come earlier to wait in line for a spot on the seating list. The food is a set menu that changes every Tuesday, so you can sit back and relax as they bring out a variety of authentic northern Thai dishes.  Be warned: it's very spicy; you'll be thankful for the plentiful white rice on offer.
