I myself am not Thai but some friends of mine are and this is where they took me for authentic Thai cuisine. It was fantastic! I highly recommend the Beef Nam Tok which I cannot find at ANY other Thai restaurant. It's charbroil beef with rice powder, onion, chili and spicy lime juice and it's just the right blend of spice and tang. If you like Thai food, or have never tried it and want to give it a shot, I would highly recommend Khun Dang.
Pros: Great food
Cons: Not a large dining room
