Can anyone help identify this TT turn?

Hello this is my first post.  I inherited photos and slides from the 1971 TT which I’d very much like to identify.
This slide is marked ‘TT’ but the bikes look more like production racers than GP bikes? so wondering if this is the Manx GP?
I am obviously not local to the Isle of Man (sorry for that) and I’ve perused many online images of many locations on the island,
but cannot find any building that looks remotely similar to the one in the photo .. possibly torn down?

Brief question is… can anyone please identify the name of this corner and the establishment in the background?
TIA, regards and happy new year, steve
