Tapatinis, across from the Marine Barracks on 8th and I Sts. SE, is the place to go for martinis. From the classics to the outrageous new inventions, Tapatinis serves them all well-chilled. The vibe is cool and hip, without the political geeks that typically populate Capital Hill bars. Friday happy hour offers a $25-all-you-can-drink martini special - lucky the Eastern Market metro is only a few blocks away!
