The restaurant's owner Jon Basso was known for warning his customers not to eat at his restaurant more than once a month because his hamburgers are loaded with fat. In fact customers are given hospital gowns to wear while they are eating at the restaurant.
It is the restaurant's "Quadruple Bypass Burger" that holds the Guinness World Record for the "most calorific burger" that weighs more than three pounds and contains 9, 982 calories. Flat-liner fries are also on the menu which they say are cooked in lard.
“I told him if you keep eating like this, it’s going to kill ya,” Basso said to the Las Vegas Sun. “He’d say, ’I just love your place, Jon.’ He’s the only person I know who was probably at the restaurant more than I. He’d be here every darned day.”
Basso said Alleman became a spokesman for the restaurant by standing outside asking people who were passing by to give the restaurant a try.
"The customer's just loved him,” Basso said.
Alleman became such a regular sight at the restaurant that Basso decided to use his image as "Patient John" on the menu and on merchandise he sold at the restaurant.
“I told him I couldn’t hire him, but I can throw you a free drink and burger once in a while,” Basso said.
Alleman who worked as a security guard at an abandoned high-rise construction site on the Las Vegas strip lived with his brother and according to Basso didn't have much money. When a reporter spoke to Basso on the telephone last week after Alleman suffered a heart attack his voice trembled as he spoke about his friend.
“It’s just sad when you see poor, poor people end up like this, with a hospital that just wants to pull the plug, Basso said. "I wonder if they’d be saying that to a rich family. It made me think of (the Beatles song) "Eleanor Rigby" — the most wonderful guy, he helped me out in my business, then he has a heart attack and he’s going to die. There’s no chance for recovery.”
