If you want an authentic food from Vietnam then this is the place. I've eaten here several times and A) the service is awesome B) if your not sure what to order the staff will help you and C) it's always crowded.
I've done most of he appetizers and have not had a bad one. The shrimp rolls are good. The various main dishes all seem the same but each one has subtle flavor differences that make it appear to be a completely different dish.
Can't say enough nice things about this place.
