I went for a professional day-long seminar there. The location is great to get to from all parts or chicagoland. The main room was large and well suited for the purpose. The private dining room we had was very nice and the lunch and dinner was tasty. The staff were friendly and helpful throughout the day. About the only issue was that the air conditioning was very sensitive - first too hot and then too cold. Overall, though, I wouldn't hesitate to hold a professional seminar there if I was organising one there for up to 40 people.
