I would suggest the Renaissance Harborplace Hotel.

I have note actually stayed in a room there, since I live near by, but I love the location, food, and if you get a room on a high floor... the view is amazing. The fact that it is connected to a mall doesn't hurt.

I'm in Chicago until Thursday next week, but if you're still around on Friday I'm up for a get together.
