Time Out says
Though there’s plenty to see on Burano, Gatto Nero devotees come just to eat at the seafood at this famous, quaintly pretty trat.
On colorful Burano, the azure blue façade of Trattoria al Gatto Nero is a landmark, as diners flock to this cozy, family-run eatery, open since 1946, for generous portions of fresh seafood harvested from the lagoon and the Adriatic. Menu prices reflect the fact that you’re something of a captive on Burano when lunch or dinner rolls around, but this is Venice after all, where meals rarely come cheap. Make a reservation, especially if you want to sit outside by the canal.
Time Out tip: For an only-on-the-island dish, try the Risotto Burano-style, made in a delicate fish broth and with a 2-person minimum. The tiramisu here is also highly praised.
