Has anyone been to Chicago? Planning a trip to the US next year and can't decide between NY and Chicago as our starting point. Have been to NY twice before (although would not be averse to going a third time!) but thought it might be a good idea to go to a city we've never been to before. I know it's famous for its architecture and that it's a great foodie city - anything else to recommend it? We'd be looking to spend maybe four days there before continuing with the rest of our trip.
