Tasca da Adriana is a small, no-frills restaurant near the old fish market, known for grilled fish at prices that reflect the local rather than tourist market. The daily specials depend on what arrived that morning — sea bass, bream, squid, sardines in season — and the set lunch is consistently good value.
The room seats about twenty people, the tables are close together, and service is brisk. This is the kind of place where the locals eat and tourists who find it feel they have discovered something. Book for dinner; lunch walk-ins are usually possible on weekdays.
