Can anyone recommend a good restaurant in the historic centre of York? The two couples (relatives from abroad) who will be travelling with DH and me are in their early 70s and they like going to stylish, traditional restaurants. Nothing too casual or noisy so no loud music. Tablecloths rather than bare tables or 'canteen-style' interior (as they call it). Traditional and a bit upmarket but not the most expensive places in town either. Ideally local or regional food. Efficient service by knowledgeable staff. Thanks.
