Sorry should have been more specific. I am staying in potomac and have a car. I don't mind taking the metro or taxi. I'm looking for a restaurant that is good for couples. Maybe 20$ to 30$ for a main. I'm open to most types of food but for the sake of narrowing the search lets say a bistro type restaurant. By cool I mean non-chain, interesting food, preferably a smaller restaurant.

I'm visiting the DC area for the week and I'm looking for some cool places to eat. Does anyone know of any good dinner places for two? Also a good coffee place (not starbucks) would be great.
