I don’t think this is quite what Tom was after but it is of niche interest. This site has three criteria for recommending pubs and they all seem quite well thought through. It lists pubs

1) where the wines and beer are well kept
2) where you can eat well
3) where your well-behaved dog is welcome to be with you while you eat.

Not being the owner of a dog (or even a pub wolf), this is of limited value to me. Any dog-owning readers out there?
