Heart Attack Grill (Las Vegas, NV)
The theme: A hospital ward for obesity
Heart Attack Grill makes no bones about its advocacy for terrible health: this is, after all, a place where patrons are encouraged to wear hospital gowns and wheeled around by waitresses who look like they work in a Hooters that doubles as a hospital cafeteria. Hell, customers over 350lbs eat free, and the high-calorie burgers come paired with high-sugar drinks from the full bar.
Safe House (Milwaukee, WI)
The theme: Spies
If Bond, Bourne, and Archer quit the spy game and opened a bar... well, they'd probably spend a lot of time beating the crap out of each other at 3am. But they'd do it in a place that looks a lot like this Milwaukee institution, which maintains the facade of a secret safe house despite being one of the city's best-known attractions. You need a password to get into the old-school lounge, but if you don't know it, you can get through the door by completing some goofy task for the doorman.
