Restaurante Tarawasi
$$
This homey seafood joint has a lounge that looks like your grandma's living room, with lots of local crafts hanging from the walls. Portions are huge, and prices reasonable: try the arroz con mariscos (seafood with rice), and enjoy the views of the bay as you linger afterward. Even if you're not interested in the beach at Tortugas, this makes a nice refueling stop en route to Trujillo or Chiclayo.
