York is a wonderful City. It is historic but also has a thriving shopping centre.
Along with open top buses you can wander round the city walls and take the riverside walk
Due to the large amount of tourism in York there are a many Restaurants Pubs and Bars I would be happy to recommend any of them to your tastes
York Minster is the medieval church at it's heart and there is also a wonderful example of a medieval street nearby.
York Castle Museum is a real treasure along with The National Railway Museum
There is also easy access from York to the Dales and the Moors along with the Yorkshire Coast
