Lively community pub

Located in Thornhill, a lovely northern suburb of Cardiff just south of Caerphilly, we have attractions on our doorstep.  Nearby is Parc Cefn Onn, a beautiful country park which is perfect for walking the dog – and we’ll be there at the end of it to offer you a refreshing pint!

When you step inside you can always expect a warm welcome.  We are open-plan and the log fires lit in the winter create a cosy atmosphere.  Outside we have a large beer garden and a covered, decked seating area which is great for those of you who like to be outdoors rain or shine. Children too love the big gardens to run around and play in. We really are the hub of the community.

We run the local charity committee and often throw family fun days and golf days which are great fun for a lovely cause.  We also have fantastic charity raffles and lotteries for you to get involved in.

There’s lot’s going on throughout the week from showing all live sporting fixtures on Sky Sports and poker nights on Mondays, through to quiz nights on both Sundays and Tuesdays. We also have a very competitive local pool and darts team.

Make sure you like us on Facebook and follow us on Twitter, to keep up to date with what’s going on. There is never a dull day here at the Pendragon.

We are also proud to offer a fantastic range of function and event packages to cater for all occasions. From formal, three course sit-down meals with arrival drinks, to an evening buffet with accompanying entertainment, we would love you to see what we have to offer.

For your no-obligation appointment with our special events coordinator, contact us on 029 2061 0550 or email



The Cask Marque Award is an accreditation which guarantees guests the perfect pint of cask ale, every time. All the cask ales on sale are tested twice a year by a qualified assessor for temperature, appearance, aroma and taste and every beer must reach the required standard in order for the licensee to pass the inspection. Mystery visits may be carried out at any time and feedback is invited from the public.

Cask Marque is an independent, non-profit making organisation formed in 1998 with the aim of improving beer quality in British pubs through the accreditation scheme, training courses on cellar management and the setting of industry standards through a series of beer quality charters, including cellar management, glass-cleanliness and line cleaning.

Over 10,000 pubs hold the Award and each one participates in the ‘World’s Biggest Ale Trail’. This allows drinkers to scan the Cask Marque certificates in the pubs using their phone and the more scans they make, the more prizes they win. Download the CaskFinder App to join the fun!
