Hey! My husband and I are taking a quickie vacation in Chicago and will only be there from about 9 am to 6 pm. Any good breakfast/lunch/general attractions we can't miss? Thanks!!

cafe baci for breakfast on michigan ave across fom the "bean" in the milleniumpark . Cheesefactory under the hancock building is great for lunch

I would do the Art Institute. I know your trip has prob come and gone, but for others: The Modern Wing is now open. Then go to China Grill on Michigan (further north) or to The Gage (also has outdoor seating and near the AI). Farther away is The Italian Village. It is still in the Loop, though.
If you are looking for cheaper eats not too far from the AI, go to Gold Coast Dogs (char dog, cheddar fries) on Wabash kitty corner from Macy's.
You might also try the Chicago Architecture Fdn on Michigan. The walking tours are great!

As Gertie & Traveltina51 have told you the ones i was thinking of i will say and as you most likely now know since i see the post date lol 9 hours is not near enough time to truly enjoy Chi-town
