The Essential Jewish Delis in Philly - Eater Philly
"University City’s Koch’s Deli has been serving the neighborhood and hungry college students since 1966. It takes a minute to get a sandwich since they’re all made to order with freshly sliced meat (the place is known for its corned beef and pastrami), but free samples for those waiting help pass the time. Each local college has a sandwich dedicated to it, like the double decker Penn Special with corned beef, pastrami, tongue, sweet muenster, coleslaw, and Russian dressing on rye." - Sarah Maiellano
