Faith Bible Chapel at 52nd(?)/Ward is AWESOME! I took my son last year and they are a huge church so they have LOTS of FREE activities. they have "jumpers" just as you go in the church, games where the kids earn candy in their "big" gym, after you cross the bridge they have another smaller gym with activities and games. they have food you can buy too. check them out. i think their website is faithbiblechapel.org
good luck
