The Gibson helped to usher in the speakeasy craze within the District, which thankfully has subsided to some degree, with only the strongest of the bunch surviving. While The Gibson does have an unmarked entrance and a strict stance about its reservations, one of the reasons it remains is that the bar was always first and foremost about the quality of its drinks. A seasonal lineup of libations is dozens deep, while guests are also encouraged to be open its preferences and have the bartenders craft something up. THE DRINK TO DRINK: The Oldies But Goodies lineup is made up of The Gibson classics. Try the Scorched Earth, with Laphroaig 10-year-old scotch, Bénédictine, Domaine de Canton ginger liqueur and absinthe. KNOW BEFORE YOU GO: Reservations are recommended, but walk-ins have some space allotted as well. The Gibson is tucked away behind an unmarked black door.
