I have been there and I will go again no problem. The reason? The city art gallery is to die for, both the architecture and the contents. It is built on the edge of Lake Michigan and looks like a huge seabird just taking off. In the evening to music, it slowly folds its wings up, tucks its head under its wing and goes to sleep till morning. The architecture is by Calatraves (Barcelona airport). But there was a Saarinen wing built earlier!
Apart from two or three rooms full of Georgia OKeefe, there are Braques, Picassos, Kandinskys (lots), a Rembrandt or two and an impressive photographic collection.
So start saving! See you there! Never mind what the classes are!
Isn't it great?
