Coming from New York (city and central), pizza is a big deal to me.
Moving to Pittsburgh, I definitely had some serious pizza withdrawals when I moved down to the city for school.
If not for R&B's, I would definitely still be feeling these effects. Yes, it's pricey at full menu price, but with the College Special option for students (or even anyone looking like a student, I've never really been asked to show ID when ordering) you can't go wrong.
Don't get me wrong, it's no New York style pizza but the taste leaves something to be said for. Something about the flavor is certainly memorable (in a good way, that is).
