One of our great secret experiences that we had, thanks to Trafalgar, was eating dinner in a castle turned winery and olive oil estate still fuctioning as such. We had a tour of the castle, which is still a private residence and was built long ago for the banking family that once rivaled the Medici's.
The 80 year old grandmother of the family made the food for all 52 of us. It was the best meal we had the whole trip. I can't say how many times I filled my plate and wine glass!
