You come to O Grove to eat shellfish. The town has dozens of restaurants — most of them clustered along the harbourside Avenida do Beiramar — and a serious one almost everywhere will serve percebes (goose barnacles, the most expensive and most prized), navajas (razor clams), mejillones (mussels — the local ones are world class), vieiras (scallops), pulpo á feira (octopus the Galician way, on a wooden plate with paprika and olive oil), camarones (small shrimp), and lubrigantes (Atlantic lobster).
Pair with cool, salt-sharp Albariño wine from the surrounding D.O. Rías Baixas — the wine region that surrounds O Grove on three sides.
