The Heart Attack Grill in Las Vegas saw a woman collapse in the restaurant on Saturday after she ate a "Double Bypass Burger," one of the restaurant's highest-calorie dishes, Fox5 News Las Vegas reported.
The incident is the second collapse at the fat-celebrating restaurant in the past two months. In February, a man fell ill while eating a "Triple Bypass Burger" and had to be wheeled out of the restaurant by emergency workers.
The woman who was hospitalized Saturday had also been smoking and drinking a margarita before the incident, according to Fox5.
"We attract an avant-garde clientele — thrill seekers, risk takers," the restaurant's owner Jon Basso told the Los Angeles Times, adding that his restaurant "attracts people who don't really take good care of their health."
The woman, apparently in her mid-forties, is doing well and recovering in the hospital, Basso told ABC News.
The restaurant's burgers range from the Single Bypass (one burger patty) to the Quadruple Bypass, which has four half-pound patties and eight slices of American cheese, msnbc.com reported. The quadruple clocks in at over 9,000 calories, and has been dubbed the most caloric sandwich in the world by the Guinness Book of World Records.

However, there is no medical evidence that consuming the restaurant's lard- and cream-laden menu items could cause an immediate heart attack, according to ABC News.
“There is some evidence that a high-fat meal can transiently affect the blood vessels – but little support for the idea that a high-fat meal can trigger a heart attack,” said Dr. Harlan Krumholz, a professor of medicine at Yale University, told ABC. “Poor diet certainly does seem that it can contribute to risk over time, but no one has yet shown that it has an immediate effect."
