Hey Everyone ---
Thanks for all of the great suggestions. My mom in law sent me this e-mail:
I'm back from Chicago. As feared, the competition for reservations in Chicago restaurants was wicked. My friends and I ended up going to One Sixtyblue, and were very pleased. Our reservation was at 7:00 and when we arrived the restaurant wasn't even half full, but by 10:00 it was packed with people waiting. The decor is contemporary with an open kitchen (which, of course I like). The four of us shared a duck a la orange confit appetizer, which was both generous and excellent and my goal will be to find a way to replicate it. My friends had snapper, tuna, and veal and all said the entrees were outstanding. I ordered arctic char and would rate it among the top 8-10 fish meals I've had. The desserts focus on, but are not exclusively chocolate. Although I'm not a dessert person, I had the hot chocolate cake. It was quite good, but too much to finish (my friends helped clean the plate). Two of my friends also had chocolate desserts and felt they were okay. A Neapolitan ordered by the fourth person was judged the best. One person ordered a speciality hot coco drink and loved it. Since the four of us live and work in different parts of the country and see one another infrequently, we enjoy the opportunity for a leisurely dinner. However, there was a bit of a wait between the appetizer and main course. A variety of servers and managers came by to attend to us and apologize for the delay but no concession was made on the bill, which for four people was a very reasonable $190 something before tip. Actually, of the four of us only two are interested in finding and trying new wines. My friend had a glass of pinot that she thought was fine but not magical. I passed on the wine. We recommended the restaurant to friends who also were attending the conference.
Thanks a million for all the suggestions!
