I have been to this place several times though have never eaten in the restaurant. They also have a plant shop, craft shops even an ice cream shop and like all good places of this type they have loos. You can wander around and visit the animals or take a walk, they do antiques, in fact, seemingly ideal as a destination for people of any age, but... There is a BUT.. The owner has just been prosecuted for food hygiene offences. They had a check and the results were woefully inadequate. They were given a plan of action and on the next check improvements were not sufficient to avoid being prosecuted.
