I'm coming to Chicago with a friend on Friday to do some field research for a new business we are opening at home. We are women in our late 30s and we will be touring stores all day. We will have a lot to discuss when we finally pause for a meal at the end of the day and we need a great place to relax, unwind, and rehash the day, Cuisine can be just about anything, but we need to be able to hear each other and make notes without disturbing the experience of other diners (although we'd like a somewhat lively atmosphere). We will be staying on North Michigan Ave. but we have a car or will cab it. Also, we prefer a place we can go without a reservation because we don't known what time we'll be done (although a short wait at the bar would be fine).
