Pizza delivery in Peterborough
Personally I really like the 241 Pizza at Parkhill and George (but can't vouch for the 241 at George near Sherbrooke). We usually ask for light cheese and well done. Tasty old school pie. They also have a walk in special, a single medium 3 topping for just over $10 bucks including tax, if you will go get it.
Night Kitchen at Hunter and Aylmer is a thin crust that gets a lot of love. I haven't seen the reason for this though.
