At the Heart Attack Grill, those over 350lbs eat for free. If you're less than 350lbs, eat enough Quadruple Bypass Burgers at the Heart Attack Grill and it won't be too long before you're eating for free too.

On Saturday night, one man learned the hard way that the taste worth dying for is no joke after he suffered from a heart attack at the Las Vegas establishment.

Witnesses said the man, in his 40s, was tackling the grill's notorious Triple Bypass Burger when his symptoms started.

Amateur video of EMTs wheeling the man out of the restaurant was posted on several Web sites as many expressed outrage.

I actually felt horrible for the gentleman because the tourists were taking photos of him as if it were some type of stunt, the establishment's owner told Fox News. Even with our own morbid sense of humor, we would never pull a stunt like that.

The Arizona-based chain caused a stir in Sin City when it opened last October because of its shameless glorification of fatty, high calorie food.

The Heart Attack Grill is a themed restaurant - and the theme isn't exactly subtle. The restaurant looks like a hospital, customers are patients, waitresses are nurses, and food orders are prescriptions. The restaurant has become internationally famous for embracing and promoting an unhealthy diet of incredibly large hamburgers.

The menu includes the Single, Double, Triple and Quadruple Bypass Burgers, ranging from half a pound to two pounds of beef. The Quadruple Bypass Burger with fries and a milkshake, the restaurant's signature meal, is said to have around 8,000 calories. It consists of four half-pound burger patties topped with cheese, bacon and no lettuce (lettuce is for wimps). Finish it, and you'll be provided with free wheelchair service out of the restaurant - a good idea considering you've just eaten roughly four days' worth of food for most people.

You'd have to walk about 80 miles to burn off that meal at an average of 100 calories per mile.

The menu also includes Flatliner Fries (cooked in pure lard), Lucky Strike no filter cigarettes, Pabst Blue Ribbon Beer, Butterfat Milkshakes, full sugar Coca-Cola, and candy cigarettes for the kids.

The Heart Attack Grill was conceived in December of 2005, but locations in Dallas, Tex. and Chandler, Ariz. have since closed.

The restaurant was founded by Dr. Jon, a non AMA-recognized physician, who flips burgers in a white doctor's lab coat. The nutritional pornographer claims that the restaurant is in a constant state of defense against various activist groups and branches of state governments.

Dr. Jon says he is just playing the role of villain in order to draw more attention to America's obesity problems.

You're intelligent if you don't eat our food, he said in October when the Las Vegas location opened up. If people pondered what I'm doing, they'd realize I'm creating a mockery of this. When you hop on that scale and you're 350 pounds and we give you a free burger and people cheer, what's really going on? We're singling you out as a freak. On the one hand, I could try to defend myself ethically and call myself a crusader that's trying to wake up America and conduct an intervention on obesity. That's half true. The other half is I'm an entrepreneur trying to make a buck, plain and simple.

Saturday's heart attack is not the first to taint the establishment. Dr. Jon's restaurant was marred by the death of its 29-year-old 575-pound former spokesman. He died last March of obesity-related issues.

Ironically, the chain's slogan is A Taste Worth Dying For.

The Heart Attack Grill diet is not for everyone, a telephone recording at the restaurant warns. Side effects may include sudden weight gain, repeated increase in wardrobe size, back pain, male breast growth, loss of sexual partners, lung cancer, tooth decay, liver sclerosis, stroke and an inability to see your penis. In some cases, mild death may occur.

Dr. Jon claims his honest advertising is refreshing in a world of fast food mysteries.

The only thing I can say in my defense is: If you compare me to Burger King and McDonald's, I'm honest and they aren't, he said in October.

It says right on my door: 'Caution, bad for your health.'
