Not arcade related:
One of the museums there currently has the King Tut exhibit through December, the Museum is near Soldier Field. I plan on checking it out when I am in Chicago in December for a Bears Game.....GO BEARS!
That would be the Field Museum, right next to Shedd Aquarium, another popular Chicago tourist spot. One thing to keep in mind, be prepared to wait. I think it takes about 3 hours just to get in to see the Tut exhibit (though they do offer advance tickets to cut down on the wait time). They also have
Sue, the largest, most complete T. Rex skeleton.

And while they don't offer tours, Chicago is also home to Midway games, WMS Gaming (formerly Williams) and High Voltage Software, makers of the
Family Guy video game.
