IT'S FIVE DOLLAR PIZZA!!!
Okay, I'll be the first to admit that Sorrento's is not the best or classiest pizza joint in Pittsburgh. But it's cheap and open late (until around 3 on the weekend). For college students this place is always a good choice....especially after a late night of partying. After around 10 is when the place really gets packed, mostly because of their $5 large pizza deal (starts at 8PM and ends at closing).
The pizza is okay (it's neither outstanding nor disgusting), but I've definitely paid more for much worse in Pittsburgh. It has never been under-cooked and is ready pretty quickly. If you are doing a late night pick-up I would suggest calling in your order to avoid waiting in line surrounded by super drunk college kids (although the conversations you can't help but overhear are pretty funny). I would say splurge and pay the extra $1 for their super yummy BUTTERMILK RANCH (if I could I would probably drink it...andI basically do...) The ranch is ADDICTIVE so I don't mind paying a bit extra. The pizza is hot and super cheesy with a thin crust and okay sauce.
I've had times when I've literally eaten a whole box by myself with two containers of ranch (cuz the guys didn't want to share) and I loved every moment of it.....even though my stomach wasn't too happy. I'd say give it a try! Instead of paying $3 for a slice, grab a box or two with some friends and stop by the 24-hour Rite-Aid for 2 for $3 2-Liter Pepsi.
