This hotel restaurant on the pedestrian street is a lovely space, with high ceilings, attentive waistcoat-and-tie staff and an old-fashioned feel. There's a huge menu that covers the range of fish (both locally caught and from the sea), steaks, pasta, chicken and crepes, with a few Spanish dishes thrown in to justify the name. The wine list is a winner, too.
