Its slogan is "Taste Worth Dying For." This week, a spokesman for the Heart Attack Grill died of a heart attack.
On its Facebook page -- the Las Vegas restaurant said 52-year-old John Alleman was taken off life support Monday after suffering a heart attack on Friday.
Officials for the home of "flatliner fries" and the "quadruple bypass burger" said he had been its spokesman for the past year and a half.
In 2011, when the restaurant was in Chandler, its other spokesman Blair River -- weighing 572 pounds -- died at the age of 29.
And at the Las Vegas location last year, two customers suffered medical conditions, including a man who had an apparent heart attack.
