The 21 Club
The 21 Club, commonly known as 21, is one of NYC's original upscale speakeasies. Fun fact - every president since FDR, with the exception of George Bush, has dined at 21, as well as a consistent crowd of celebs. Its old-school New York vibes mixed with toy-airplanes on the ceilings and Martinis on the checkered bar will have you running back for more (but don't forget your dinner jacket).
