Just as much as the politics that go on, partying is an imporant piece of D.C. culture. But what happens when you get tired of going to the same ol' spot on the same ol' block? It's time to switch things up. Bust out UrbanDaddy and pick the time, day, and part of town you want to head out to, and the app will give you a selection of spots that fit your mood. UrbanDaddy only supports a select number of cities, and D.C. happens to be one of them. Now you don't have an excuse to show your friends around the next time they come visit the capital.
