This is a wonderful place to visit. Ulnaby Hall has its own farm shop with locally produced goodies, fruit, veg, meat, etc, together with a delicious tearoom with fresh food made there and then for you. If you want there's home made icecream too.
Ulnaby Hall Farm is part of a buried medieval village, which you can explore after with the children (Time Team did it on the telly too) or you can have a tractor ride around the farm. There's a playground for the kids to enjoy whilst the grownups have another cup of tea and a homemade scone.
