So far I really like NU (which is the only school I can speak on). One of the things that sold me was the Bluhm Clinic, specifically the Center on Wrongful Convictions.
Also, and I know it sounds cliche, I really like the level of diversity at the school--there are so many different backgrounds, experiences, nationalities, and political views represented. Not every prof is a bleeding heart and not every student owns a Che Guevara t-shirt. I also like the fact that it's a slightly older incoming class than most schools because they don't admit many students straight out of undergrad. I could really tell the difference compared to other schools I visited such as Berkeley.
I've found my professors to be very accessible, my peers supportive (no cutthroats), and there are more activities than you'll ever have time for.
Oh yeah, there's free food almost every day...
Highest tuition in the country, yet you still have to pay $.05 a page to print on campus.
The writing class (CLR) makes you work like a dog for only 2 credits.
The lighting in the library sucks.
Chicago is really friggin' cold.
