To review 666 Fifth Avenue seems appropriate, this being my 666th review. Erected in 1957, when it was known as the Tishman building, the rather conventional office tower was enhanced by a number of contributions - including the elevator bank ceilings and floors and the waterfall screen in the lobby - by sculptor Isamu Noguchi.
