Comming to Chicago. Where should I go?
 

So,... for my birthday a couple weeks ago my girlfriend gave me a trip to Chicago. She is putting us up at The Hard Rock Hotel in The Loop and got us tickets to the Cubs versus my very own GIANTS!!! This is probably the coolest thing ever, well besides an AP, TBE, and protune. Can you guys tell me where to go, what to see, where to eat. Don't know what is there besides Wrigley and The Sears Tower.

TIA

Oh, I also want to take her to a nice dinner. is there a nice romantic place you guys recommend?
