Polyglot French-Polish chef Arthur Marcinkiewicz is easily the most classically trained cook in the Cusco region and visiting his restaurant is a special treat. The elegant, formal eatery in a beautifully converted casona focuses on classical French dishes with preparations that stay mostly true to form, a miracle in Cusco where many ingredients are near impossible to get. While Le Soleil is by far more expensive than anything else in Cusco right now, for the quality it’s still a reasonable deal for the five- or seven-course tasting menus or the dishes like duck à l’orange or lamb shank that’s cooked for 16 hours with smoked lentils and pear purée with lavender. The wine list is entirely French.
