Please see recent Telegraph review of pubs in the UK.
Ones of note (especially) in this part of Northumberland are:
The Feathers Inn - which has just won RSPCA award 2011 for the Best Pub and Best Gastropub in Britain and strangely not included in The Daily Telegraph Review of UK Pubs.
Carts Bog Inn
Lord Crewe Arms
Will write more about pubs anon. Thought you might be interested in reading about these ones!
