They mention rotting floor like a turntable. Perhaps some of the towers
to, but I did not see any specifics.

A revolving restaurant or rotating restaurant is usually a tower
restaurant eating space designed to rest atop a broad circular revolving
platform that operates as a large turntable. The building remains
stationary and the diners are carried on the revolving floor. The
revolving rate varies between one and three times per hour and enables
patrons to enjoy a panoramic view without leaving their seats. The slow
speed only requires less than a horsepower.[1] Such restaurants are
often located on upper stories of hotels, communication towers, and
skyscrapers.



Also a lot have closed or no longer rotate. Must be a maintenance
nightmare.
