If you feel like picnicking on some of the cold cuts (salumi), cheeses and other fresh foods on display in the delicatessens and market stalls off Piazza Maggiore, then Osteria del Sole at a tiny street could be a perfect venue. This traditional wine-drinkers' osteria (something of a rarity nowadays) invites you to bring along your own food. Popular with locals and travelers alike, it can get full, especially on Saturday (and don't expect to find soft drinks).
