The city was awesome, but the school was very mediocre. I also noticed a rather snobby attitude in some of the people there (though that could have just been the school).
Overall though, I met a good friend in Chicago, and I have many great memories of weekends spent exploring the city. Overall, it was worht it for me.
P.S.-there are some super, super little restaurants in the city. Always keep your eyes open, some places look cheap-o, but are in fact delicious.
