There are restaurants that serve decadent, if unhealthy, meals. And then there’s the Heart Attack Grill in Las Vegas.

Billed as a hospital-themed restaurant (though no actual medical professionals work there), Heart Attack Grill serves huge burgers ranging from the Single Bypass Burger (half a pound) to the Octuple Bypass Burger (four pounds). The Flatliner Fries are cooked in pure lard and there are butterfat milkshakes and hot dogs, as well. The food isn’t the only unhealthy highlight: unfiltered Lucky Strike cigarettes are also available.

It’s no wonder there are signs like the one that reads, “Cash only because you might die before the check clears.”

The Heart Attack Grill is controversial, to say the least. It’s had brush-ups with people who think that the language surrounding the business is dangerous as well as the food. It’s easy to see why. Anyone who weighs more than 350 pounds and is willing to step on a cattle scale in front of the restaurant to prove it gets unlimited free food. The website notes that customers are “patients,” orders are “prescriptions,” and waitresses are “nurses” who spank anyone who doesn’t finish their meal.

Anyone who finishes the Quadruple Bypass Burger (9,983 calories, according to the Guinness World Records) gets a free wheelchair service.

It’s not all talk, either. Someone eating at the restaurant had a real heart attack in February 2012, and another in April 2012. A spokesperson died in 2013 from a heart attack while leaving the restaurant after two years of promoting it.

If you want to see for yourself, Heart Attack Grill is located at 450 Fremont St. in Las Vegas, Nevada.
