It's just a guess, but I'd say the Horse Shoe tavern or the Angel tavern were better places to visit than the Vulture or the Young Devil--all actual tavern names.
According to the book, Stage Coach and Tavern Days, not all tavern names remained the same. Around the time of 1776 in the USA, lions became unpopular, so the Golden Lion tavern became the Yellow Cat. An easy switch when words aren't involved.
I also found mention of the Conkey tavern, named for its owner. I can't see that on a sign board and I suspect it didn't have a placard out front, but was named by the locals.
Apparently tavern names fascinate more than one person because there's a Random Tavern Name generator online. I'm sure most people can think of a tavern name on their own...
