A solid slice for a decent price, Cora Pizza is a good standby when other places let you down. While they offer significantly less variety in slice toppings (at least of the by-the-slice kind) than next door rival Papa Ceo, I have to say that it's still a damn good slice in and of itself.
Maybe the closest thing you can find in the core for a NY style slice, Cora offers the kind of drippy, gooey slice that every U of T coed dreams about grabbing after class. The inside of the restaurant is decidedly tiny, but unless it's the dead of winter you'd probably not sit in the steamy shop to eat unless you're in a rush. That's what the bench out front and any number of nearby parks are for.
The slice specials center around the garlic and pepperoni slices - I am more of a garlic fan but the pepperoni slice holds its own as well. I've tried the handful of specialty slices a few times and would just as soon choose the more basic offerings. If I want a slice with lots of quality toppings I'd just as soon head next door to Ceo's. Both are good for their own reasons, and this magical little corner of pizza goodness is a slap in the face to all the cardboard, rubbery-cheesed Pizza Pizzas of the world.
