Chicago Dining Recommendations

[johnbeans]

My parents are coming to Chicago in a week, and I’d like to take them out to the nicest place that doesn’t require a jacket. My parents have a traditional contemporary American-ish taste, so a sushi bar is out of the question unless it’s a fusion thing. Upscale Asian cuisine is also fine as long as it has more to offer than sushi. I know about metromix and chicagoreader, but am curious to hear some recommendations from OOT.
