I'll be visiting for a long weekend, doing most of my eating in the District proper though I'll be staying part of the time in Silver Spring. More-casual fare preferred; atmosphere not so important; any neighborhood OK, at least while I'm walking about solo.
I've explored New York's multinational foodways in depth, but I'm sure that Washington has much to offer that's less familiar to me. Burmese, Ethiopian (for breakfast), and American Southern are three possible avenues of chow. What else would you suggest? Thanks in advance.
