Fast Delivery All Day!

Keystone pizza is the BEST PIZZA PLACE in the Tri-State area. Always great quality pizza always friendly service and great food choices. I will continue to drive 10 miles and pass by other neighborhood pizza shops just to order here. AAA Quality!

Would rate 6-stars if I could!!! This place is amazing, food is always so well flavored and wait time isn’t long at all. Favorite place for wings, pizza, and salads... That’s everything!

Best pizza spot in the tri-state area. Food is delicious. Worth your money! Don’t waste your time with any other pizza spot in the Upper Darby area

Just ordered a peperoni pizza beef/pork. It was delicious! Best I’ve had in Upper Darby! The delivery driver was really upbeat, friendly, and sweet. Definitely will order again!

Best wings anywhere!

Fast, friendly, and great food!!!

Great food. Fast delivery!!!
