A favourite of mine for years. Full of ethnic Vietnamese (some talking English by now), plus odd besandalled White. Pho and only Pho (meat+noodle soup) but first-class, what you came for!
Basic decor, (Ok, like cafeteria).
Food comes very quick.
Very low price.
Washingtonian magazine Very Best or more recently Best Bargain Restaurant every year 1987-2012
What more can I say?
