Some other early Sega arcades:
"Metropolis" was situated in a basement of Hamley's (the big London toy store), circa November 1992. No idea what the story was there, but there was merchandise!

(wiki page in a bit)
"SegaFolies" opened in Spring 1993 in a Marseilles (France) branch of Virgin Megastores. Good luck finding anything on that.
When Euro Disney opened (now Disneyland Paris) there was also a Sega venue of some description which apparently counts as the first Sega-branded arcade in Europe. Except I can't prove it existed yet. Quite a lot about the construction of Euro Disney though - it's almost interesting.
EDIT: oop from a press release in 1996:
