Restaurante Rincon del Pescador is a small seafood restaurant tucked into the streets of San Andres, away from the main tourist strip. Reviews make the fish of the day the clearest reason to go, with one visitor calling it the best fish they had in Tenerife. Cold vegetable soup with crispy bacon, octopus and cheese with honey and corn also get specific mentions.
Most visits describe friendly service, fair prices and generous portions, even when the room is full. The useful caveat is that feedback is not perfectly uniform: one visitor found the seafood rubbery, the sangria bottled rather than homemade, and portions small for the price. That stands apart from the broader pattern, but it is worth keeping in mind.
