Also wins the award for most embodying the concept of the Slow Food movement and most amazing setting. We arrived in the evening, the lone table of diners in the centre of the piazza. The excellent food is served by your host who begins with a lively explanation of each dish with how his grandmother would prepare this dish or about the ingredients which he grows himself. Dinner finishes with an invitation to try the local Nocino (walnut liqueur) or homemade grappa. Goose and pasta with pecorino cheese, chilli, and pears are the house specialties.
