Keystone Pizza - Upper Darby

I placed an order for delivery. I ordered a cheese steak with very specific toppings and instructions. I can honestly say, this was the BEST sandwich I've ever had!!! My order arrived early. The sandwich was so hot I had to let it sit for awhile until it cooled off. It was a lot larger than I expected, prepared EXACTLY as I requested, and it was delicious!!!

Best pizza hands down and it don't make u feel heavy with tons of

Best Pizza ever I recommend coming here for take out and lunch

This place used to have the best cheesesteaks in upper darby. now their cheesesteaks have no flavor whatsoever.
