18th street, Adams Morgan, on Saturday afternoon.
The scene is quite different come nightfall – according to (as ever) wikipedia:
Adams Morgan also has become a thriving spot for night life, with a number of bars and clubs featuring live music. Over 90 establishments possess liquor licenses, putting it on level with other popular nightlife areas like Georgetown and Dupont Circle. Local stores along the 18th Street corridor were rapidly replaced with late-night establishments, leading to a moratorium on new liquor licenses by the Alcohol Beverage Control Board in 2000 after successful lobbying by resident groups. The moratorium was renewed in 2004, but eased to allow new restaurant licenses.
