The other reviews mirror my thoughts on McGill Pizza.  It's in no way, shape, or form, the pinnacle of fine dining; however, if you're looking for a quick, reasonably priced bite to eat, it certainly fits the bill.  I tend to go for the chicken pita or the veggie pizza.  The pizza is particularly good, with a thin crust and a myriad of toppings.  For a lunch between classes, this is a nice change from the food courts, chain restaurants, and McGill cafeterias.
