The 1920s are about to roar at historic St. Louis Union Station. A pop-up cocktail experience is coming to Grand Hall January 25 and will be offered through March 6. The pop-up will be open everyday from 4pm-11pm.

Opened in 1894, St. Louis Union Station was the largest and busiest train terminal in the country, serving 22 railroads with trains headed to all corners of the nation. During the Prohibition era, from 1919 to 1933, the Station was a hub of activity for traveling crowds, including flappers, gangsters, lawmakers and bootleggers. F. Scott Fitzgerald's novel The Great Gatsby was released in 1922, defining the Jazz Age and documenting the freewheeling lifestyle of the decade.

Union Station and its Grand Hall are restored to their original glory with decorative elements such as architect Theodore Link's lighted torch-bearing Art Nouveau ladies, stained glass windows and a gilded 65-foot-tall barrel-vaulted ceiling. Union Station's award-winning light shows will play hourly on the Grand Hall ceiling during Opulence.

Today St. Louis Union Station is a family entertainment destination with attractions including the St. Louis Aquarium and the 200-foot-tall St. Louis Wheel as well as the 567-room St. Louis Union Station Hotel, a Curio Collection by Hilton.

St. Louis Union Station is located at 1820 Market St., St. Louis, MO 63103.
