I think I've been there. The Wicked Lady at Nomansland Common nearby used to be a beer festival pub with a room at the back being converted to what is nowadays a micropub style cold room but with a counter and room for probably a couple of dozen casks. The John's Bunions was very much a side issue and I don't remember anything about it.
McMullen got rid of a load of smaller rural pubs in the 1990s, including the Moletrap and the Carpenters Arms. A travesty!
