“Best friends. Best life,” Lohan, who dated Morton in 2006, wrote in an Instagram tribute Sunday accompanied by a photo of the pair.
“Harry was a visionary and restaurateur ahead of his time, and his contributions, both professionally to our brand and personally to those he worked with, were numerous,” the Mexican food chain Pink Taco said in a statement, per The Associated Press.
Morton had the restaurant business in his blood. His dad, Peter, co-founded Hard Rock Cafe, and his grandfather, Arnie, established the Morton’s steakhouse chain.
Harry Morton opened his first Pink Taco at the Hard Rock in Las Vegas in 1999. A subsequent location in Scottsdale, Arizona, closed a few years after local controversy over the chain’s double entendre name. Pink Taco’s current locations include Los Angeles, Chicago and Boston.
