Speakeasy-style bars have been popping up all over Mexico City of late, and in the age of social media, it's hardly a surprise that none of them stays a secret for very long. Still, nearly a year after it opened, Hanky Panky has managed to remain somewhat below the radar. With a members-only model (don't worry; it IS possible to get a membership, which carries a nominal fee), the team behind the Prohibition-inspired Hanky Panky says the exclusivity allows staff to really interact with guests, providing them with information and guidance about what they're drinking. So how DO you get that membership? Check out Hanky Panky's Facebook page, of course!
