The cheesesteak, conceived in South Philadelphia, will be one of the main attractions at this year’s 9th Street Italian Market Festival, a highlight of the annual South Philly social calendar.

It will host its first-ever cheesesteak competition, whose field of entrants will be determined by public nominations. Organizers said the shops will be invited to participate “based on both pedigree and fan voting.” A panel will pick the winner during judging at 11 a.m. May 20 on the main stage. The festival runs May 20 and 21.
