To get into the bar’s side entrance, you’ll need the password (they post it on the bar’s Instagram story). (Of course the National Museum of Organized Crime and Law Enforcement has a speakeasy.) There’s lots of mob paraphernalia (including the actual phone booth from inside the Four Deuces brothel and saloon in Chicago, run by Jonny Torrio and Al Capone in the ’20s) and an actual distillery that turns out three kinds of moonshine. There are plenty to choose from in Vegas, but the Underground at the Mob Museum is a favorite. Do I really want to go through a secret entrance, give a password for admittance, and sip a cocktail in a dark room with a bunch of strangers who were cool enough to know how to get in? Yes. The allure of a speakeasy never gets old.
