Osteria alla Frasca
Far from the madding San Marco crowds, this tiny eatery nestled under a grapevine on a remote campiello charms before you even taste the seafood (think: grilled seppie [cuttlefish], canoce [mantis shrimp], excellent baccalà mantecato, or sarde in saor [sweet-and-sour sardines]). Wines are an important part of the meal here; ask for a recommendation from the ample list of predominantly regional selections. With limited indoor seating, La Frasca encloses and heats their outdoor terrace to accommodate winter diners.
