Fellini, on 3 Norte just off the Plaza Sucre, is a popular mid-range restaurant that sits somewhere between Italian and Chilean: pasta dishes, salads, grilled fish, and decent pizzas all share the menu. The dining room is bright and welcoming and the staff are used to dealing with visitors.
Portions are generous and the prices are fair by local standards. It is a useful default if you find yourself near the centre at lunchtime and do not want to walk further.
