This is the best *overall* Vietnamese restaurant in Chinatown. The pho is average but the menu contains more options than others. The rice and vermicelli dishes are all very good, as are the not-so-often-ordered (i.e. snail broth noodle soup, beef stew, banh xeo [coconut crepe], banh guon [steamed rice noodle], etc.
If you are looking for a bowl of pho, this might not be the best spot for you. If you want to venture off the beaten path a little bit, then go here, turn to a random page and point to a dish!
Try the dinner for two with the spicy and sour soup and clay pot catfish, its fantastic.
