Divino Pecado on San Martín is one of central Viña's most established Italian restaurants, with a strong following among locals as much as visitors. The menu runs to handmade pasta, gnocchi, risotto, and a few grilled meat and fish main courses; the wine list is short but well chosen.
The dining room is small and unfussy and fills up early in the season; book ahead at weekends, especially during the song festival. Service is friendly and the kitchen knows what it is doing.
