I love Alfredos Pizza in University Mall. The white pizza especially is delicious, and the by-the-slice offerings always look fresh (I've only ordered whole pies myself).
The pizza is flavorful and not drenched in sauce. Also, it's not too greasy, which I really appreciate. The crust has a good texture, neither too thick or thin, and never soggy in the middle.
This pizza is more expensive than some other nearby options, but in my opinion it's totally worth it.
