BM, now that is stretching the brain cells. I know I visited LATCC and remember lunch but no memory of why. Best guess was 1988 and it just seemed so spartan compared with the splendour of the ground floor. The wardrobes on stilts to avoid the rooms being sub standard. The sloping top of the windows with no curtain or blinds. But overall the contrast.
I am sure that was well after your time.
