Some Prohibition-Era speakeasies required more than a password – they issued membership cards used to identify the bearer as a true, and maybe dues-paying member.
Did speakeasies have food?
Some speakeasies catered to the urban “upper crust,” like New York's notorious 21 Club. One way of ensuring that patrons didn't leave inebriated, thus drawing unwanted attention to the secret saloons, was to serve patrons small amounts of food throughout the night.
What was served at speakeasies?
To help soak up the booze and drive up sales, some enterprising speakeasy proprietors began offering more than just gin fizzes, whiskey smashes, martinis and other popular cocktails of the day.
