Skip the dull first-level “jungle room.” Instead, check out the main room upstairs, where—in addition to the large fish tanks that give the bar its name—you’ll find a sizable selection of beers ranging from Milwaukee’s finest to Belgian favorites Chimay and De Koninck—all on tap. The pearl at the Reef is the heated roof deck overlooking a vista of downtown DC—a view well worth seeing even if you have to bulldoze through Adams Morgan crowds on the weekend.
