I am at the airport waiting to board my flight to ORD. I am staying at the Peninsula tonight. I need a recommendation of a "not to miss" place that is open late where I can eat tonight. I am open to all suggestions -- fancy or not. If Weiner Circle is the right place, so be it. I just need to know, as someone without a lot of Chicago experience, where I should go so as to not risk wasting my one meal in town.
