MrsG and I will be in Chicago for a few days this week, and while we're there we'd like to go out to a nice dinner. Neither of us has ever been to the city, so I'm soliciting restaurant advice from the SF crowd. We're not looking for a place for Thanksgiving dinner, so it doesn't have to be somewhere that will be open that day. The only caveat is that I would prefer something other than a steakhouse. If there's one that just can't be missed I'm all ears, but we have access to a decent steakhouse in Atlanta, and we travel to Tampa enough to hit Bern's if we really want a steak. We're staying a couple blocks north of the river, in the area of the Magnificent Mile, if that helps with advice. I'm also interested in any other general Chicago input the SFers may have. However, I've been looking over an earlier Chicago thread from this summer, and that's been pretty informative on sightseeing-type stuff.
