The second unofficial spokesman for the Heart Attack Grill in downtown Las Vegas has died from an apparent heart attack.

John Alleman suffered a heart attack last week as he waited at the bus stop in front of the restaurant, located inside the Neonopolis at Fremont Street and Las Vegas Boulevard.

Alleman, 52, was taken off life support shortly after 1 p.m. on Monday, said restaurant owner Jon Basso. "He lived a very full life," said Basso. "He will be missed."

Heart Attack Grill is famous for its high-calorie menu that includes a record-breaking 9,982-calorie, 3-pound Quadruple Bypass Burger.

Since the restaurant opened in October 2011, Basso said Alleman would stand outside its doors every day, coaxing customers in. Soon enough, Alleman became a fixture at the restaurant he loved, Basso said.
