The United States is the birthplace of unique business ideas, which is why there are many eateries here with incredibly distinct styles.
The Cave, Richland, MO
If you've ever wanted to dine in a cave like Batman, The Cave restaurant offers 250 seats overlooking the Gasconade River just for you. Prepare your appetite for their American-style beefsteak menu – stuffed mushrooms, fried pickles, jalapeño poppers, and mac'n'cheese made with bread. Additionally, guests can canoe before their meal or take a famous Missouri paddleboat ride. For added fun, request a table near a lifelike mountain lion model for some photo ops.

Harvey Washbangers, College Station, Texas
Here, you can use laundry machines and steam services to clean your clothes. Paired with a menu featuring the eatery's signature Banger burgers, nachos, Buffalo wings, and chorizo queso – pork sausage with cheese. And of course, we must mention one of the best collections of beer – the drink made right at the bar – in all of Texas.

Bors Hede Inne, Carnation, WA
As the hub of the Camlann Medieval Village, doubling as a living museum representing an English village in 1376, Bors Hede Inne (Boar’s Head Inne in modern English) serves guests with servers embodying the spirit of old English minstrels, dishes dating back to the 14th century like frenberry pye (from pork, chicken, and cranberries) or sanc dragon (chicken in cinnamon sauce with almonds).

Safe House, Milwaukee
Upon arrival, you'll be astonished to find yourself at the headquarters of the International Exports LLC. The venue boasts hidden doors and passages, shoe phones, and other spy paraphernalia, along with waitstaff styled after the Cold War era.

Fritz’s Railroad Restaurant, Kansas City, MO
You don't have to be a train enthusiast or a child to enjoy a restaurant with a... railroad theme. Order via a rotary phone, and a train engine nicknamed Skat Kat running on tracks overhead will deliver your food – burgers and fries, salads, and smoothies.

Magic Restroom Café, Los Angeles
Inspired by the Modern Toilet restaurant chain in Taipei – and clearly with the imagination of an 8-year-old – Magic Restroom Café is the pinnacle of toilet humor. Diners sit atop actual toilets with Taiwanese dishes served on porcelain throne-like trays, making dishes like braised beef and curry rice even more peculiar.

The Airplane Restaurant, Colorado Springs, CO
The owners of this restaurant repurposed a retired Boeing KC-97 into a space for a bar and eatery, adorned with countless aviation memorabilia. The menu items are also aviation-themed, with playful wordplay, like the Philly Flyer sandwich or nachos named Air Tower.
