Brunch/Tea suggestions for a 60th Birthday!

My Mom is turning 60 in a few months. I am interested in planning a brunch or tea or something else fun for a group of women. Does anyone have any good ideas? I would prefer to keep it to the north/northwest burbs seeing as everyone lives around here. Any help would be greatly appreciated. I would like a private room! Someone has suggested Sage Grill in Highwood. Any thoughts? THANKS!
