If you want a pepperoni pizza in NDG, this is the place. They use thick STRIPS of pepperoni, not the paper-thin slices of almost-bologna that now permeate the Montreal pizza landscape.
I've also had the Pendeli's Special, which is terrific as well.
FYI, Van Horne Pizza in Outremont also uses the same type of pepperoni, and is almost as good. The sauce and crust at Pendeli's is better though.
