The best restaurants serving British food in Shaftesbury Newport South Wales

Visited the restaurant at Sainsbury's Newport today with family. Very disappointed with the adult meals. The ham was very poor quality,chips were over cooked and not very nice at all. Worst of all were the two cold fried eggs. When I asked a staff member for freshly cooked eggs as ours were cold. She was not very polite, our meal went back and the eggs were slightly better., Today's standard was well below what's acceptable. Will think twice before eating there again.
