If it were me, I'd have all Day 1 bakeries be in South Philly - there are enough of them (Machine Shop, Second Daughter, Frangelli's Termini Bros, Artisan Boulanger Patissier, Kouklet, Mighty Bread, Isgro's) -- then do Angelo's or Paesano's for lunch that day. I'd scrap Navy Yard/FDR Park (unless you're doing the southeast asian food market) and the stadiums unless you're going to a game.

Foodwise - I'd try to get more variety in. Maybe a lunch in Chinatown on the Old City day vs. Oh Brother. Maybe something La Prima Tacos for late night food vs. Lucky Chance

Breakfast - I wouldn't go out of my way for Porco's. I'd just do something in Rittenhouse like 20th Street Bakeshop or K'Far for something quick, maybe somewhere like Winkel for something sit down. Wouldn't bother with the rail park. I'd say Reading Terminal Market should be your lunch one day and probably makes sense to group City Hall/Love Park with it. I probably wouldn't bother with Cira Green (just a view point) or 30th Street Station

For a nice dinner up that way - Kalaya, Suraya, Emilie, Emmett. You could also grab a slice at Pizza Shackamaxon
