We found that Volterra differed from other places we know in Tuscany in that as a general rule most of the inhabitants see their role as parting the maximum amount of cash from their visitors with the mimimum of service and civility. A notable exception was a restaurant called Amarcord just across the road from the hotel which was fantastic. We had a very expensive, very slow, very poor dinner at Enoteca Del Duca.
To enjoy Volterra you need to be very, very enthusiastic about the Etruscans. The main musuem is very old fashioned and to be avoided unless you like rooms and rooms of arrowheads and pots.
