I worked in the Control Tower Bar, aka Dodge, on the ground floor from about 1980 - 1983 when it closed.
Many hours of fun and stories never to be told
. Curtains pulled at closing time punters left by the front door and those in the know re-entered around the back, Happy Days!
The bar was a staff bar that had a public license, the guys who ran it also ran the Queen's Building bar.
