re: Things to do in Chicago

There's an absolute shitload to do for tourists.

Willis Tower (Sears Tower), the John Hancock building (go to the bar there instead of the observation deck), Navy Pier, definitely do an "architecture tour" (its a boat ride), Wrigley Field (you've got that covered), the Magnificent Mile.

The Museum of Art is great, The Field Museum, the Aquarium.

Just scratching the surface. You really can't run out of things to do.

The Purple Pig
Girl & the Goat
