Don't let the ghetto shopping center steer you away...it's a great place. Definitely a no frills type place...this is the real deal. It was very evident by most of the patrons actually being Vietnamese, you know it must be good.
You just walk in and sit anywhere that's open and someone will bring you their menu which is quite extensive. I had my favorite, which is Pho Tai. The broth was perfect, and had a pretty complex flavor profile. Hard to explain, but some pho broth's are very 1-dimensional...this one was exceptionally flavorful. They don't skimp on the meat either, which some places tend to do. I've been to Vietnamese restaurants all over the valley, and although I have still never been to Da Vang...I'd venture to say this might be the best pho in Phoenix. Tastes darn close to the stuff you get in CA, in Garden Grove/Westminster/Little Saigon.
Also, it is dirt cheap! $4.50 for a big delicious bowl of pho tai....yum. I'll be back soon for sure.
