A 54-year-old man who spent his days touting the greasy pleasures of the Heart Attack Grill in Las Vegas has died of an apparent heart attack, the restaurant’s owner said.

John Alleman was waiting for a bus outside the downtown grill last week when he collapsed, Jon Basso told NBC News. Alleman was hospitalized for several days, but died on Monday at Sunrise Hospital and Medical Center, a spokeswoman confirmed.

 He’s the second unofficial spokesman for the unabashedly unhealthy restaurant to die in the past two years, according to press reports.
