A diner at the Heart Attack Grill in Las Vegas, NV, got what he paid for on Saturday: He suffered a coronary while enjoying the restaurant's signature Triple Bypass Burger.

The man -- who is alive and recovering -- began to complain of chest pains while eating the burger.

He was having the sweats and shaking, 'Nurse' Bridgett, a waitress at the Heart Attack Grill, told FOX 5 News.

Doctor' Jon Basson, the restaurant's owner -- who appears to take the staff role-playing very seriously --  said he thought it was a joke at first.

One of the nurses came back to me and said, 'Dr. Jon, we've got a patient who's in trouble, Basson told FOX 5. He immediately called the paramedics and EMTs arrived on the scene.

The gentleman could barely talk, said Basso. He was sweating, suffering. Anyone with an ounce of compassion would've felt for him.

Tourists were taking photos of him as if it were some type of stunt, Basso said. Even with our own morbid sense of humor, we would never pull a stunt like that.

The unfortunate restaurant patron may be grateful he didn't order an even unhealthier item on the Heart Attack Grill's menu: The Quadruple Bypass Burger meal has 8,000 calories.

A sign on the entrance of the Heart Attack Grill reads Cash Only: Becase You Might Die Before the Check Clears. Diners -- who are dubbed Patients -- who weigh over 350 lbs eat for free. The restaurant's web site boasts about Taste worth dying for!

Area residents indicated the warnings might not be taken seriously, and could even be counterproductive.

It says right on the door, it's hazardous to your health, CJ Beeman told FOX 5 while dining at the restaurant Tuesday night.

I don't think I would walk into a place, even if it's called the Heart Attack Grill, and order food, and expect that I was going to have a heart attack, Las Vegas resident Debbie Kaye said.

But Basso seems to be shaken by the incident -- and he's taking all of the blame.

It's not anything to be taken lightly, he told the Los Angeles Times, complaining that those mocking the Patient' should be sensitive to the poor guy -- he's got a mom somewhere.

I don't mind if people demonize me because that's part of our shtick -- we're the bad guys of the hamburger industry, Basso said, but did not indicate any plans to reconsider the restaurant's current menu or policies.
