Gnomad asks (a long way up the thread and about two years ago!) about a Lake District pub called the Drunken Duck, which a I remember from years ago, and which apparently derives from a landlady who used throw throw the beer slops out, where they'd be lapped up by the fowl around the pub. The last I heard of it, it's now an expensive restaurant of the kind that draws broadsheet food writers from London.

Also in the Lake District, I've enjoyed the Golden Rule in Ambleside (which has golden ruler hanging outside. Gold-coloured rather than gold, I suspect) and the Mortal Man at Troutbeck, near Windermere.

The last explains its name as being from the verse:
"O mortal man, that lives by bread,
What is it that makes thy nose so red?
Thou silly fool, that looks't so pale,
Tis drinking Sally Birkett's ale."
