Perfect for match-day fixtures

The Cornwall is the perfect pub for enjoying a couple of drinks and watching your favourite sporting events from Sky Sports and BT Sports on our big screens.

Expect a friendly and welcoming atmosphere for you and your friends to relax in and socialise, with drink offers available throughout the week.  If it’s the hustle and bustle of the bar area that you fancy, or the more relaxing vibe in our lounge, we’ve got it all covered.

We pride ourselves on being a traditional community pub with traditional community spirit. We are involved in a number of charitable causes. To us, raising money means having fun, so whether it’s the latest Welsh Band or Snail Racing events we’re always getting involved. 

You can keep in touch with us and the great events that we have by liking us on Facebook, or following us on Twitter.


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!
