On April 21, 1986, locked vaults found in the hotel were the subject of a live television program called The Mystery of Al Capone's Vaults, which received 30 million viewers.

The building was demolished in 1995, despite its presence on the list of Chicago landmarks and the National Register of Historic Places.
