What recommendations do you have for someone visiting Chicago for the first time?

My sweetie and I will be in Chicago from April 8–14, 2011… I’ve never been, and he was there for a brief visit years ago.

If you live in the area, are you aware of any special events or festivals happening during that time? I am up for meeting fellow jellies, so I will be posting in the “Meta” section about a potential get-together.

We enjoy art and music – especially jazz. We love food and are rather adventurous (he more than I). We also like architecture and structures.

Yes, I will go through all the similar questions that have been asked previously; but I am hoping to learn about current and upcoming events, so I thought it would be best to ask again with the specific time frame.

Thanks for your input!
