Culinary legends are made in this leading font of gastronomic innovation, an ideal place to try outnouveau renditions of Peruvian standards including alpaca ribs, ceviche, or perhaps your first cuy (guinea pig). It's in an old sillar (white volcanic rock) building with wooden balconies, stained glass and a resident pianist.
Two doors down (San Francisco 315), sister restaurant Parrilla de Zingaro specializes in Argentinian-style meats with equally splendid results.
