America's Strangest Restaurants (PHOTOS)

"I am probably the only restaurateur in the entire world who is unapologetically telling you that my food is bad for you, and that you should stay away from it," Heart Attack Grill's Jon Basso recently said after one of his regulars suffered (you guessed it) a massive heart attack on his post-meal bus ride home.

With waitresses dressed as sexy nurses and a Guinness World Record for "Most Calorific Burger," this Las Vegas attraction is surely an only-in-America experience. But in a country that birthed the bloomin' onion, it's not the only weird eatery America has to offer. Strange restaurants abound from coast to coast, from a toilet-themed café in the suburbs of Los Angeles to ninja villages in New York City and an actual cave in the Midwest.

On your next trip, eat at these strange restaurants and let your foodie freak flag fly.
