My Kind of Town [Chicago Is]

After nearly 11 years in New York I'm packing up the family and moving back to Chicago [my home town].  As it's been quite a while since I last lived in the Windy City I was hoping that any readers who live in / spend a lot of time in Chicago can make some suggestions for restaurants, things to do, etc.  We have a 5 month old son, so our beat is less swank and more chill.  If you've got anything feel free to drop them in the comments section of this post.  Greatly appreciated.
