Reputedly the best in the city, Penso is actually just a shop (unlike some of the 'pasticceria' which function as cafés too), but there is ample seating a couple of blocks away by the water. Perhaps their guests would never leave if they had chairs and tables inside, given that their cakes, pastries, chocolates, every imaginable sweet local delight, are top notch. Located a few streets south-west of Piazza Unità d'Italia.
