Mehran Restaurant, Pakistani-style. Tried lunch buffet. It's a best buy-- only $8 total (tax included) for a decent buffet of Pakistani style food, this in DC proper. (I am told it differs from Indian by virtue of slightly less sweet sauces.) Naan is fresh and good, always hot, although they keep it in the tandoor a bit too long and the outside is a bit burnt. The best is their vegetable, which tye make well. One problem that keeps this from being too good: They kept the tandoori chicken under a plastic cover, so that the steam make the outside soggy when you finally take one out.
Good for the price
