I'm brining a group of about 20-25 people to Chicago in May and we do two dinners as a part of our conference. We're having one dinner in the restaurant in the Marriott (called "The Restaurant" in fact). I'm looking for suggestions for the second dinner, on a Thursday night, preferably a private room. The group is fairly adventurous in terms of food (at least for a group, that is) and we'll have at least one vegetarian (no meat or fish). We had good luck at our last meeting in Baltimore with Tapas and have done well with traditional coursed menus as well, so I feel like anything is open so long as it's good and is in a relatively nice setting. Price range between $50 and $70 per person not including drinks, tax and tip.
Thanks in advance!
