Wow!
Finally got round to reading your blog.What an amazing amount of research you put into this.I remember the one on Lothian road in the early 90s.I went in there regularly and had the good fortune of playing STUN RUNNER,Space invaders 91,Tiger Heli,Raiden and an MVS 4 slot.Up the back there was pinball machines including Dr Who and a Gunblade.You walked in to the building and there was a whole big long row of fruities or "puggies" as the Scots like to say.Then left and right were a couple of raised areas with the machines (maybe 15 in total) then walk up the back and you had change kiosk then toilet to the left and to the right was the pinballs (4 or so) and bigger cabs like the aforementioned Gunblade and even a Sega Time Traveller.Loved this place but was always slightly scared of using the toilet incase I got mugged or worse 🤔
