In 1957, The Theater Cafe was converted to an ice skating rink, called Rainbo Arena, which was a practice rink for the Chicago Blackhawks including the year they won the 1961 Stanley Cup. The Rainbo Arena was also a training rink for several Olympic figure skaters, and during much of the 1960s was the only indoor hockey rink in the Chicago area open to the public. Several hockey leagues were headquartered at Rainbo, and particularly on weekends, hockey-playing groups would rent the ice at all hours of the day and night.
