Serving Peruvian classics in high style, La Mar is part of superchef Gastón Acurio's empire. Start with a tart pisco sour – they pack a punch, but in a good way. The degustación plate lets you try four varieties of causas or ceviche . Potato causas come delicate and creamy. For timider palates, arroz chaufa (fried rice) is fluffy and flavorful. The setting is sleek.
