Union Station 
is one of the busiest stations in the country. At its peak in 1917, more than 79,000 trains passed through. In the 1930s it was the scene of a mob massacre where five FBI agents were killed as well as the mobster they were after. The bullet holes are still visible on the exterior granite of the building.

Inside, the building has undergone a $250 million restoration and now houses Science City, a hands-on children’s science museum; a theatre complex; several restaurants; and a planetarium. We got off the Trolley Tour here and enjoyed an hour of just browsing. The building itself is beautiful, and the chandeliers and ceiling are magnificent.

We had to stop for a chocolate fix at the Rocky Mountain Chocolate Company, and there is a huge science museum gift shop. Right now, they have a Titanic Exhibit going on, which you can visit for $12; some of the objects are on display in the terminal.
This building has loads to offer, especially to families and can be visited in an hour or 2, depending on whether you visit the science museum. There are also tours offered of the Station. The station is open 6am to midnight. The station is connected with the Crown Center by the Link.
