We visited on a snowy day and just missed the jam making class. The shop was great fun and the kids enjoyed trying the various jams. The beet jam and pear jam at highly recommended.
The food at the cafe was ok. Japanese style paella or curry. Decent flavour but not overly exciting.
This is probably worth a visit when the weather is better as the were and short walks etc. The drive there through and agricultural areas was pleasant and relaxing.
