I am visiting Chicago for the first time next week, for a conference, and am looking for suggestions of places to eat on Tuesday and Wednesday nights. I am late 30s, female, and want to find places with great food but also fun, bustling atmospheres where I can just wander in and eat at the bar. I'm definitely not looking for anything fancy, though I am not trying to stay within any particular price range, either. I live in Boston and love smaller, more casual neighborhood-y places (I eat mostly in the South End, for anyone familiar with that area of the city), but since I'll be by myself I also want the atmosphere to be comfortable and entertaining. Probably not looking for "off the beaten path" places, or anything too specifically ethnic (though I understand there is a lot of good regional Mexican, and I would be open to sushi). I am staying somewhere around the city center but would be willing to hop a cab if necessary. Sorry for the lack of specifics re: type of food -- for this trip, someplace I'll have a good time at the bar and eat great food, whatever the style, is most important.
