Just turn down the lights, put a gin cocktail on the menu, and suddenly, you're a secret Prohibition bar.
We want to salute the bars that actually provide a little mystery, which is why we're sharing this list of the best secret bars in the United States and around the world. Naturally, we're not suggesting no one's heard of these places -- if they were full-blown secrets, they'd be out of business -- but rather, we're tipping our (possibly bowler?) hats to them for their efforts to shroud the operation. May their passwords be ever-changing and their phone numbers be forever unlisted.
