In 2003, Michael DiLeonardo testified in a tax-evasion case involving mobster Peter Gotti, in which he said that Ciprianis gave $120,000 to the Gambino crime family to make union problems at the Rainbow Room disappear. The charges were never confirmed. A year later, the Ciprianis sued 30 Rockefeller Plaza's landlord, Tishman Speyer, for the latter's plan to place metal detectors at the lobby entrance to the Rainbow Room's elevator bank. Tishman Speyer cited security measures implemented after the September 11, 2001, attacks as the reason for installing metal detectors, but the Ciprianis said that the detectors would "damage the reputation and business of the Rainbow Room" by causing potential guests to wait for up to an hour before entering the restaurant.
