A man reportedly suffered a heart attack while eating the “Triple Bypass Burger” on Saturday at a Las Vegas restaurant that serves “Bypass” burgers, “Flatliner” fries and free meals to people who weigh over 350 pounds.

An amateur video posted on Youtube shows the unidentified man being wheeled out of the downtown Heart Attack Grill restaurant on a stretcher after he collapsed in the restaurant that employees told KVVU-TV FOX5 looked like a heart attack.

Restaurant owner “Doctor” Jon Basso told the news station that he initially thought it was a joke when a waitress who told him a customer eating a Triple Bypass burger, which estimated to contain about 6,000 calories, was sweating and shaking.

However he immediately called 911 and paramedics had arrived quickly to treat and take the man to the hospital, and Basso said that the man is still recovering although details of his medical condition and name had not been released.

“Tourists were taking photos of him as if it were some type of stunt,” Basso told KVVU-TV FOX5. “Even with our own morbid sense of humor, we would never pull a stunt like that.”

Basso had also said that there have been a “variety of incidents” at the restaurant, but Saturday was the first time there was a full-scale coronary.

The restaurant opened last October and is notorious for serving high-calorie, high-fat foods. The restaurant even has a sign that says that indicates says, “Caution! This establishment is bad for your health,” and the just last March the restaurant’s spokesperson Blair River died at 29-years-old from pneumonia. River had reportedly been 575 pounds, according to USA Today.
