Looking for a good place to eat after work, meeting friends who work in Maryland half way. Sadly, having lived in DC for 5 years, I've stayed close to home or ventured further south and am quite unfamiliar with the territory north of Cleveland Park. Recomendations for any type of restaurant would be great. Happy hour specials are a plus, but not required. Looking for somewhere casual, not fancy and a little more upscale than a chain sandwich shop. Thanks a ton!
