Has nobody mentioned (read the whole thread) "The Nobody Inn" at Doddiscombsleigh in Devon? We used to go there regularly when we lived in Devon many 40-odd years ago. Seems it still exists, as it has a website.
Nearer home now, Boozer in 2003 mentioned "The Black Bitch" in Linlithgow: not just part of the town's coat of arms but a local legend, which is portrayed on the walls of the lounge bar. (And a very non-PC friend calls it "The Winnie Mandela").
And where I live, in Balerno, SW Edinburgh, one of the local pubs is known as "The Honky" (real name "Malleny Arms"). Again the reason, in local history is shoen in a sign outside the pub. It dates from WW2 when US servicemen were stationed at Kirknewton airfield a few miles down the road, and christened it "The Honky-tonk".
The other pub, The Grey Horse, is known to many as "Brow's" after the landlady who retired possibly as much as 20 years ago.
