One of our favorite Philly lunches is a picnic and our favorite supplier is Di Bruno Brothers. The fun is picking something new. We always start at the cheese counter, where we ask for something seasonal/unusual/limited. They are happy to recommend, always let you sample and will happily cut “picnic” size portions. We have had a lot of delicious cheeses, but the most fun was the Austrian sheep’s milk rolled in edible, dried flowers harvested from the sheep’s own alpine meadow. 
They also have a delicious charcuterie (again – advice/samples/picnic sized portions are no problem). Our favorite discovery here was the molè salami. Final stops for bread, fruit and dessert. It’s not cheap (usually $15-20 pp), but the quality and adventure are worth it! We usually visit the Center City/Chestnut Street store (which is their largest and has prepared foods, a coffee bar, and a restaurant upstairs), but the original Italian Market store still has many of the original fixtures and is beautiful. Each of the stores carries a slightly different selection.
Tobey says: Favorite! Picnics are always fun.
