I know this is pretty far-reaching, but I feel like I gotta ask anyway:
Old School Chowhound from DC prizes hole-in-the-wall finds. Looking for one meal anywhere this board covers. This might be a Monday, so let me know if a place is usually closed on Mondays.
I used to read more, but I am not so up on things the last three years or so.
Here are places, cuisines that I I would consider if I don't get any replies:
Sichuan, Spicy and Tasty? others?
Blue Ribbon Bakery? or anything else really good.
