I did some research on it –

“Pennine Tower was used as a restaurant but closed to the general public around the late 1980’s/early 1990s. The tower was closed due to Health and Safety reasons. Apparently you need two alternative exits in case of a fire and with just one lift and one staircase coupled with a kitchen the risk is just too high.

Also, drivers found it distracting when lit up at night and thought it was ugly, resembling a UFO.

It opened in 1965, originally owned by Toprank, then Granada and then in 2000 they rebranded into Moto which is what it is today.

The tower is now empty or used as offices.”
