In Chi town for the 4th - any locals with tips or suggestions?

[rjmacs]

Partner and I are in Chicago til Tuesday, and plan to do the Art Institute, Field Museum, Millennium Park, etc. Could use suggestions for cheap eats, any other "don't miss" spots near downtown, etc. Both vegetarian, so sorry - no steakhouses for us. We love pizza, though, so point us to the good spots... :biggrin:

Hope everyone is having a good weekend!
