The Heart Attack Grill based in Las Vegas, Nevada, gained worldwide notoriety for its high-calorie menu which included the record-breaking 9,982-calorie, 3-pound Quadruple Bypass Burger.

Indeed the Heart Attack Grill’s slogan is “Taste Worth Dying For” and it would seem that they’re not wrong there. 

The menu also includes the colourfully named Flatliner Fries, Full Sugar Coke and the awesome (or wait, is that awful?) sounding Butterfat Shake.The place even apparently actively encourages the sale and consumption of no-filter cigarettes.

John Alleman – a security guard by trade – was such a fan of the restaurant that he volunteered his free time by standing outside spruiking the food and greeting other customers as they came through the doors.

The 52-year old was even featured on some of the restaurants promotional clothing and was given the nickname ‘Patient John’ because he was there so often. 

Heart Attack Grill owner John Basso paid tribute to Alleman, but said that his death wouldn’t cause any changes in his restaurant or its’ food.

“He never missed a day, even on Christmas,” restaurant owner Jon Basso said. “He lived, ate and breathed the Heart Attack Grill.”

“It isn’t going to stop us from what we’re doing. People have got to live their lives,” he said.

Despite eating so much at the restaurant Mr Alleman reportedly only weighed 180lbs (about 80kg’s) and didn’t seem to be in too bad health.

Alas, poor Alleman was not the first Heart Attack Grill aficionado/mascot to have fallen foul of the greasy, fatty foods they so craved.

In 2011, another loyal customer, the 260kg Blair River, died of flu-related pneumonia.

And in April last year, a woman in her 40s collapsed eating a double bypass burger, smoking cigarettes and having a margarita.

Although the Heart Attack Grill makes all of it’s waitresses dress up like “sexy nurses”, so it can’t be all bad.
