I'm a student who lived in Rome last year - went and ate everywhere - and Rome is great for getting a quick slice of pizza, but the best by far is Lo Zozzone (or The Dirty One). For €3 you can have a huge slice of fresh white pizza, with whatever you want in it. Great quality and great price - I miss it so much.
Lo Zozzone, 32 Via del Teatro Pace,
(4 min walk form Piazza Navona)
