This post, like the last two, also deals with the use of the coat of arms of the dei Medici family. Alas, I’m not at all sure how proud they would be to find their arms being used to hawk food, however. (Especially Lorenzo!)
Still, heraldry is heraldry, wherever you might run across it, and to whatever purpose it might be placed. Even trying to attract customers to one or another food emporium.
