I have been a customer of the restaurant since I was a little kid and my parents would take me here. After just two or three trips, they will remember your name, where you are from, what you like to order, how you want it cooked, and anything else you volunteer to tell them. It's pretty amazing. The food is fantastic, and much better than any other vietnamese restaurant I have found in phoenix. The bun has a lot more vegtables and substance than most I have tried. The peanut sauce and spring roll sauce are both incredible.
It's your typical dive asian place. Busted up floor tiles, glass table tops, and next to no atmosphere. It's all about the food, and the perfect service (assuming they are not busy.) It's also very inexpensive. A family of 4 can eat dinner for less than 40 bucks including soft drinks. The only downside I can think of is the neighborhood, it is located next to a coin-op laundry which attracts lots of ghetto types.
