re: Going to Chicago, what are things to do?

We are going Thanksgiving weekend to a concert Friday and Saturday night. Friday I have 5:45 reservations at girl and the goat. Saturday we will try to hit Au Cheval for lunch and Pequods for dinner (open to other suggestions as we had pequods last year when we went), then a bar late night I suppose. Staying at the River Hotel. Im guessing it will be pretty cold so any inside activities would be welcome (not to derail your thread)... I would like to hit the purple pig, so may try that as well, i guess well just have to see

When we went last summer we hit Wrigley, architectural boat tour, some bar on the 92nd (i think) floor, lincoln park zoo, and really just walked around a lot as well.
