Okay! Provisionally, dinner at 6, which will allow people who get off work to migrate to the restaurant -- I'll look for a place right off the CTA Blue Line that goes straight to the airport, just in case traffic is dicey and it would be quicker to put you on the train after dinner. I'll do some emailing and look for a suitable restaurant -- anything you miss/particularly in the mood for/would not touch with a ten-foot pole/allergic-to?
