Formerly one of New York City's best-kept secrets, this hidden speakeasy has become world famous thanks to its meticulously crafted cocktails and balance between swank and back-of-a-hotdog-joint status. Enter through a phone booth in Crif Dogs and get transported to a sexy hideaway where you can post up with inventive takes on Old Fashioneds and Sazeracs alongside waffle fries nestled in foil. Although the name insists you "Please Don't Tell," the secret's clearly out so it's best to make reservations; call to snag a spot when the lines open at 3 PM daily.
