Hey Everyone - I'm back from traveling (and to peak my head out of the Sports thread for a bit )... To answer the question about the tours - I heard the Untouchables Tour is excellent (a friend of mine recently went on it, although I've never taken it). It's about a couple of hours and you get to see lots of Chicago. They give you lots of fun mobster facts, which you all probably know anyway.

I'll probably join you guys on this tour.

Another good non-mob-related tour is the Architectural Boat Tour. You get on a boat, go up and down Chicago River and you get the history of Chicago and its buildings. I last took it my first year in college way back in 1996 and remember that it was a very good tour.
