I'm going to be in DC for a weekend - are there any signature or must-have cheap eats that I should have while I'm there (under 20 dollars a person) both including restaurants and other food stands or carts or anything? Any location within the city, or nearby outside (particularly north of the city) is fine (I will have a car).
Happy to be referred to any quintessential cheap eats threads DC hounds may know that I may have missed as well. Thanks.
I posted this last year - http://chowhound.chow.com/topics/647836 - but a lot can change in a year, both with restaurants and with chowounders - any updates? Are the places listed here still good? New places or places that weren't mentioned before? Thanks.
