The entrance to the museum is the restored lobby of the old train station. Wonderful exhibits trace the history of omaha...Warren Buffett's family grocery store, the World Fair, historic films, great traveling exhibits. This museum is part of the Smithsonian organization..so the traveling exhibits are spectacular. There is a fun old fashioned soda fountain where you can get an ice cream float. Great gift shop. Especially recommend visiting during Christmas season...the huge Christmas tree in the lobby (Tree at Union Station is usually two+stories tall) and special exhibits and events are wonderful and have become part of our family traditions.
