Gonna be up in Chicago in 2 weeks for a concert (Pitchfork Music Festival), probably going to stay a bit on sunday too (maybe) Friday is booked with the show, but Saturday I'm looking for somethings to do/see around town that are cheapish, fun, and good to do with the girlfriend. Not really into the bar scene so you can exclude that, but other things would be great we are already considering Shedd Aquarium.
Also looking for cheapish hotel accomodations in the same area, so any suggestions on what is good and safe would be appreciated
