In 1993, former press agent Sam Bushman recalled:
The Ink Spots were just starting. Their record “If I Didn’t Care” made them superstars overnight. But they were committed to come back to the Rathskeller several times more at their old price.
Little Rathskeller was located at the corner of Broad and Spruce.
