We'll be traveling to Philly next week for 2 dinners and 2 lunches. We'll be staying in Center City. I did get a reservation at Zahav for one night. Since I went to school there ages ago, I've heard (and read) that there's now choice of great dining. I'm looking for places whose chefs that use fresh seasonal ingredients creatively. No steakhouses. Please suggest options that are also open for lunch.
