Born and raised in the windy city and go back often. Have family members flying in from all over (a total of 8) on Friday October 4 and we are all staying in the River North neighborhood. Since everyone is coming in at different times from different airports it's impossible to make a dinner reservation. Any suggestions for casual yet creative food (no tapas or pizza please) in our neck of the woods? We prefer a more quiet atmosphere with good wine and with no reservations required.
