Great to hear of the Rhostyllen two doing well and keen to promote their real ales.
New landlady Nicci at the Black Horse now has four real ales on sale and hosts plenty of community activities at the pub.. https://whatpub.com/pubs/CLW/13629/old-black-horse-rhostyllen
Just down the road at the Swan, landlady Claire has introduced a 15p CAMRA membership discount on their real ales. https://whatpub.com/pubs/CLW/13677/swan-inn-rhostyllen
It is excellent to hear that the pubs are in such good hands. Why not get the bus to visit both? You can also have a short stroll over the Clywedog to the Black Lion in Bersham and enjoy three great pubs in one trip!
