Hi,
Please help me plan some activities for my 3 day trip to the windy city! I had only been to Chicago once last year and I only had 2 days so I didn't see very much!
I am thining about trying some chicago dogs and pizza. I tried Giordano's last time but I didn't really like it that much although I loved the fact that I felt like I was eating a large cheese ball

. I am thinking about Lou Malnati's this time. Good choice?
I want to try Superdawg, but since I won't have car, my ability to travel will be limited to foot and train. I think it's going to rain/snow this weekend with temp in the teens

so I don't know what I am going to do.
I'll be staying in the River North area (Westin) and will probably go shopping on Michigan ave and check out a couple of museums..like field and contemprary art. I went up to Sears Tower last time...
Where else should I/must I go? Any recommendation is appreciated!
