Union Station is wonderful, from the small fair atmosphere on the outside and the koi pond that you can go paddle boating on, to the absolutely beautiful architecture of the inside of the restored train station. In the front entrance, there is the whisper wall, where one can be standing on one side of the building and whisper into the wall and the person on the other side of the building can hear them perfect. The shops are fun and entertaining. One of the best places in St. Louis! I would recommend any day. A five star venue!
Pros: location, surroundings, food
