“They should all be good.”
But not all are! I ate at Benares in London and it was a truly shocking experience, cold food, rubbish service, run out of food etc etc.
I would also avoid the Olive Tree in Ilkley.
Back on post… This place is in a lovely environment, the hotel is very relaxed with a country feel. You can quite often get very good deals on dinner bed and breakfast (in the michelin restaurant). As an overall package I would say it is excellent. The food is good, but fractionally down on quality of the best michelin restuarant I have eaten in which was Fischers in Derbyshire, but its only slightly less good and still leagues ahead of many restuarants.

Another alternative is http://www.vennellsrestaurant.co.uk/index.html in Masham. Not michelin starred but in the michelin guide and very good. Stay at the Black Sheep brewery, great weekend!
