Just checking that you're definitely not talking about the Mount Pleasant Inn in Llay? Only if you are we share a common interest as my GGGrandfather, Benjamin Jones, was the Inn keeper of the Llay pub in 1891!
Looking at the Llay pub on Google Earth, the bus stop in front is described as 'Burton, Mount Pleasant Inn' but not entirely sure what that means (could it just be the route that particular bus takes?)
Anyway thought I'd mention it on the off chance we were talking about the same place.
