This 50-year-old fast food chain is a Chilean institution and now has a score of restaurants around the city. This is the place to try an Italiano, a hot dog with tomatoes and avocado or, a chacarero, another Chilean favorite—a hot dog or a beef sandwich with green beans, tomato, and chili pepper. Its restaurants have no-frills decoration but are impeccably clean, and the service is fast and friendly. The chain also has a phone-in home-delivery service. Credit cards are not accepted for takeout.
