Here's an article for the Cairo hands on Groppi, the classic Italo-Swiss patisserie and tea room in Cairo. Other, and I think more accurate, accounts here and here and here. I'm pretty sure alcohol disappeared from Groppi's in the mid-70s, for example, not the 80s. I'll try to write more another time. Still playing catch-up from vacation on the day job, so brief posting today. More posts tomorrow though.
