The best that I've found is at Bettola, on Amsterdam between 79th and 80th. It's classic thin-crust woodburning stove Italian (I love the pizza with smoked mozarella and sausage) but I can't pry a friend away from the prosciutto.
For a slice, I like Sal & Carmine's on Broadway in the low 100s.

not sure if you have any geographic limitations but:
serviceable slices - freddie and peppers, big nicks, t&r, rigoletto - and yes, further uptown agree w/ sal & carmines.
pies - v&t further uptown is good but gets mixed response here..the brick oven options at celeste or bettola..and there's always patsys if you're into that.
