Fuck all the haters, I still end up coming here after a night out. No, you should not be expecting a Libretto-style Margherita where you can say "ooh, the crust is charred to an appropriate blackness - how authentic!" You get huge ass, thin slices of pie perfect for soaking up the large quantities of booze still residing in your gut.
Do heed the warnings about dining in, as you get some sketchy fucks hanging out here. But the slices are cheap, and filling, and delicious. I like the pepperoni and mushroom.
Get a slice and walk around Ryerson campus if the mood should strike you.
