Princeton is literally the only part of NJ i've been to that i like. such a beautiful suburb sandwiched between ugly highways, and if you live in the Boro you can get anywhere by walking. I have an aunt and uncle that are both lawyers that are lucky enough to afford to live there. and it really is directly in the middle of NYC and Philly, can't beat that convenience.
It really probably is the only nice part on NJ. A lot of nice bars on mainstreet, so much good food, and its just so warm and friendly. I work 5 minutes off the main street and went to college nearby. Unfortunately for now I'm stuck with an hour commute there.
