24 hrs in Chicago - recommendations

Hi all

I'm a Brit with a business trip to Chicago area coming in the next couple of weeks.  For most of the week I'll be way outside and won't have a chance to see much at all, but I've organised 24 hours in Chicago itself and was wondering two things:

- is there a decent camera shop - I'm sorely tempted to get a Fuji X-E1 while I'm there (save money over UK prices)?  I shoot with a 5D II and lenses but thinking about an X-E1 also

- any good spots for photography?  I'm thinking about doing the obvious thing and getting up the Willis Tower.  Nothing specific in the way of subjects - just be nice to capture a little of the place.

Thanks a lot in advance.

Marcus
