I'd recommend this place highly for two situations:  1.) You are on the west side of town and you want some reasonably priced grub, 2.) You've never had Vietnamese food and you want to try it out in a non-intimidating environment.  For those two things, PA is awesome!   

Nice people, decent food, and a very friendly environment. But their food doesn't stack up to the central Phoenix standard bearers.

I suppose that their score is artificially low because of the category they are competing in.  Were they the only game in town, I suspect I would have rated them much higher - just to get my hands on a Bahn Mi every now and again.
