My new favorite venue in the U street area is on 2007 14th street NW.  Marvin has dark wood floors, comfortable lounge-like chairs, a DJ booth above a dance floor, and an outside roof deck with its second bar. Inside the walls are covered in pictures of jazz greats. Most importantly, the DJ played some smokin' hot 70s funk that kept me and my dancing shoes very happy.

 In addition to its cool atmosphere and music, Marvin also has two other essential ingredients to a good time: no cover, and based on how my friends and I looked after a day of cook-out hopping, casual dress code. They also serve food there, but I was too busy getting my groove on to eat.
