In 1984-1985 I worked on the 89th floor of 2 WTC. Ebasco was there at the time, with a good amount of nuclear work.
Can’t remember what floors I’d visited for business, maybe not TOO high, but the offices never bothered me, it was just that blanking restaurant.
If you recall how it was tiered, we were seated in a banquette on the top tier, and I kept leaning back, as if, had I leaned forward, I’d have fallen out of the building, into New Jersey somewhere ;)
