In a city infamous for belt-busting temptations, this piazza-side pasticceria (pastry shop) enjoys celebrity status. While you'll find all the local classics (including a particularly luscious babà), the star attraction is the ministeriale, a dark-chocolate medallion invented in the 19th century. The ingredients of its liqueur-laced ganache filling are a closely guarded secret. Al fresco piazza seating available.
