The very extensive wine list was surprisingly lacking of a local wines: more french wines and champagnes than wines from Isola d'Elba or even Tuscany. Anyway, personally I like tasting "farm-to-fork" or local foods whenever possible. However, that's a choice of the owner ... I guess they feel differently.
