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