Going to Chi-town this week, need recommendations..

We were there last week for a long weekend. The Chicago Marathon was going on so there was a lot of people in the city. We went to the Field Museum, Shedd Aquarium, and Museum of Science & Industry. We also went to both observation decks (360 & Willis Tower), and went on a river cruise and a cruise around Lake Michigan. Of course we managed to squeeze in our picture in front of the The Bean! The Bears were out of town that weekend and we opted against a Bulls preseason game as tickets were too pricey.
As far as food we ate at Gino’s East and Pizanos for pizza. We ate at Al’s and had Italian beef sandwiches and ate hot dogs at Portillos. We also went to the Billy Goat Tavern for lunch one day and it was a good burger. All were solid meals, but the best meal we had was our last night there and we had a burger at Au Cheval. Without a doubt the best burger I have ever had!

What do you like to do? Sightsee? Prefer restaurants and bars? Not much to go on from your post.

I'd search 'Chicago' on this board and the F&B board. There are probably a dozen threads from the last few months.
