You have lots of great suggestions!
I'm just going to second two things that I would definitely do in your shoes. I've tried all the most famous Chicago Deep Dish pizzas, and Lou Malnatis is my favorite (looks like it's a favorite of most of the other posters too). I got a different one two months ago when I was in the city as the other place was right by my hotel, and I wish I had made the effort to do Lou Malnatis instead lol.
Also, especially since it doesn't take too long to do, definitely stop by Millennium Park and the Bean which is in the park. The Bean is unique and a super fun little stop. We really enjoy that, and it's a must do stop for us every time we're in the city for more than a day.
If taking a stroll the River North area -- magnificent mile area is kind of nice. It's more of a shopping area than anything. I realize you are staying elsewhere, but when I'm a tourist in the city, that's my favorite place to stay.
