Rotating bar, yes, a bit strange after you'd had a few. Had some good times in there.
I remember now, I put a drink down, turned round and it had bloody gone!
It was the Tuxedo Royale in Newcastle that had a rotating dancefloor, that combined with its pronounced list to starboard (being a boat) made any movement within the premises an adventure after a drink or two - I recall flattening many a group of ladies stepping off the rotating dance floor and falling over!
