FWIW - Kelly's is where the ISU Athletic Assn. Gamewatch is for the TCU game, up on the roof. No elevator, only stairs. Kelly's has a built in pizza joint but really no food beyond that. I would agree it's not a kid friendly place and parking is a little tougher but as for ISU-Friendly, it's hard to beat and since it's hosting the official gamewatch there's more likely to be kids there than other times. ISU newspaper articles on the wall and a long history with ISU. It's worth viewing an ISU game there at least once, even if it's not this weekend.

The Brooksider will not be very kid friendly either but the wait staff is good and the food is decent IMHO (try the buffalo chicken salad and if you're not watching your figure get the chicken fried). There was a great ISU contingent there for the Iowa game. Probably won't be quite as many tomorrow. If they will put the game on downstairs that's the place to go. At the Iowa game the upstairs and outside crowd didn't realize the game was on in the basement and there was only eight of us down there. We could hear the TV and didn't have to fight the crowd to the bathroom.
