Come for the chess. Stay for the cheesesteaks. On Thursdays from 2-6 p.m., Jersey Jo’s Philly Cheesesteaks has been hosting casual chess at its one-of-a-kind shop at 187 18th Ave SW (in the small strip mall across the Frontage Road from the McDonald’s on 2nd St. SW). Stop in for casual chess (and, really, there’s no obligation to buy any food).
