you can always catch a movie, go mini golfing.. even go to the mall for an hour.. they love claires dept. store.. it would cost 10 or less to buy something cute at claires... if you have claires in chicago.. it's a store that sells hair stuff and cute kid jewelery. How about swimming at a pool ..
or a walk by the lake. good luck.. i'm sure she will have fun..you can go get pizza and have it outside on a blanket.. like a picnic...
