If you're looking for some of the most authentic and delicious seafood in Venice, pay a visit to Antiche Carampane. Located in an unassuming building a few minutes' walk from the Rialto Bridge, this trattoria is where the locals eat when they're craving seafood-focused Venetian dishes. It's a cozy family-run restaurant with framed photos in the dining room and friendly service. The local fish, octopus, clams, shrimp, and scallops are what to order here, as it tastes about as fresh as it comes and is served in a variety of styles, including a simply prepared catch of the day. The menu here is more complex than that of the typical tourist joints, featuring traditional Venetian dishes that are not usually found outside a local's kitchen. In spring, try the fried soft-shell crabs.
