Club 33

Where it is 1313 S. Harbor Boulevard, Anaheim, California—aka Disneyland—in a nondescript housefront next to the Blue Bayou restaurant

Why you want in The Magic Kingdom is dry. Anyone craving a stiff bourbon to help make It’s a Small World a little more bearable is SOL, unless they’re members of Club 33, the secret restaurant—and bar!—behind this door.

How to get in Good luck. There’s an 8- to 12-year waiting list to join the club. Also, they now take only corporate memberships.

Safe House

Where it is 779 N. Front Street, Milwaukee, Wisconsin

Why you want in Every spy needs a refuge … preferably one that serves batter-dipped cheese curds. The plaque next to the door reads international exports, ltd. estab. 1868, but behind it is a spy-themed eatery with a secret escape route and a chair that rises up from a trapdoor in the floor.

How to get in Go to the website, click on the Top Secret Clearance Agreement to promise you won’t disclose the location, then contact Control (translation: Make a reservation).

Milk & Honey

Where it is 134 Eldridge Street, New York, behind what appears to be a sewing shop

Why you want in This is one very highbrow cocktail joint that keeps a very low profile. “Many New Yorkers assume that Milk & Honey is an urban myth,” the bar’s website says, and that’s how they like it. Order drinks with hand-cut, twice-frozen ice, and be sure to follow the code of conduct: no name-dropping, and gentlemen should not introduce themselves to ladies.

How to get in Befriend a regular or find the email address (not posted online) for reservations.

Bad Robot Productions

Where it is Somewhere in Santa Monica, California

Why you want in If you dream of personally delivering some fan mail to the production shop responsible for Fringe, Alias, and the Star Trek reboot, you have your work cut out for you. It’s harder to find than the island on Lost. But if you’re in SoCal, keep an eye peeled for an outfit called the National Typewriter Company. Hint: They do not manufacture typewriters there.

How to get in Be J.J. Abrams. Or work for J.J. Abrams. Or follow the hidden clues.

Parallel City

Where it is 140 Piazza Cavour, Naples, Italy

Why you want in The bustling city of Naples sits on top of an enormous, nearly 3,000-year-old network of caves. This particular entrance to the underground city leads to 17th-century aqueducts that were once the property of Ferdinand II, king of the Two Sicilies.

How to get in Make your way sotterraneo by heading through the unmarked doors and down the rickety WWII-era spiral staircase built by Mussolini’s civil defense program.
