Alma de Cuba chef Scott McLeod was pronounced dead at a hospital Sunday night after he was found unresponsive in a restroom at the popular Rittenhouse Square restaurant during dinner service, sources said.

Owner Stephen Starr said he did not know the cause of death. Alma de Cuba closed Monday out of respect.

McLeod, who worked in Philadelphia for at least a decade at such restaurants as Pasion, Cuba Libre, Bridget Foy's and Azafran, was a native of Louisiana. He was in his early 40s.

In 2014, while working at Cuba Libre, he won the John DeBella Comfort Food Festival.
