Okay, judging a Vietnamese restaurant on the decor is a little jaded IMHO. Ambience is certainly a factor when dining, and if that's your most pressing criteria you're probably not fit to go into most Vietnamese places.
Pholicious does a great job with their food-went their for lunch over the weekend and tried their oxtail pho which was very good. My buddy had chicken & vegetable chow fun which was also delicious. Sizable portions and the most unique serving of Thai iced coffee I think I've ever had. Almost like a half old time Italian espresso pot on top of a coffee cup that holds the coffee and condensed milk. You're supposed to stir this then add the contents to the accompanying glass of ice. Unlike dummy me who just dumped it in the ice :)
