Chicago recommendations? Extra points for pizza recommendations!

I’m headed to Chicago Thursday for a conference. I’ve been once and visited some of the main attractions (Art Institute, Field Museum, Science & Industry Museum…). What other recommendations do you have?

I’ll be staying a block or 2 east of the Magnificent Mile, so things within walking distance would be best.

Mainly looking for things to do/see and food. Any pizza-by-the-slice recommendations around there?

Money is a little tight right now for attractions (we just bought a house and we’re putting in a yard…), so the cheaper the better.

Thanks!
