No 10 was in South Tay Street from around the late 70's and all throughout the 80's.
It was a pub I never had a drink in. Passed it hundreds of times too, but only once did my mob stop off and have a nosey at it from the doorway - we looked inside, and we all went "Naaaah!", wasn't lively enough for us. It seemed like a cosy wee place for middle aged couples to spend the evening, or perhaps we just caught it on a quiet night, but off to the noisy, more youthful pubs we went!.
I recall being told back then that the folk who had No 10 also had it's politically related partner around the corner, Chequers. Not sure if it was a fact or someone just linked the 2 names, as No 10 was the actual street number of the pub, but I'm certain they had wee framed political caricatures on the walls.
Maggie Thatcher was in the real No 10 at the time which may have also influenced us in choosing to avoid it!
