Pittsburgh doesn't have many Vietnamese options. Tram's Kitchen is the only place I've ever heard people mentioning. Today I've finally visited it.
First impression: solid pho. The soup had a good flavor, though the portion is a little small. I was disappointed that they did not have tripe or tendon, but the beef was cut thinly. The menu selection is not terribly wide, but they seem at least competent with what they do have to offer.
Efficient family service. Simple ambiance. Dinner under $15.
