I highly recommend Phipps Conservatory. It is absolutely beautiful. They change some of their exhibits so there are new things to see each time. Around Christmas, they have a model railroad that kids love. If you have time, take one of the free guided tours of the conservatory and learn a little of the history. It is truly fascinating. I've been to several conservatories but Phipps is my favorite. Even better, CMU and Pitt students get in for free with their IDs.
