Buenos Aires’ culinary identity was shaped largely by the Spanish and Italian immigrants who settled in Argentina, bringing with them traditional cooking techniques and tastes. It’s no surprise, then, that Spanish and Italian restaurants continue to play an important role in the city’s gourmet scene. Avenida de Mayo, in Congreso, is home to many of the most old-fashioned and high-end Spanish restaurants. It’s a wonderfully atmospheric place to come for a long, classy lunch alongside some of the neighborhood’s well-dressed citizens. Try the set lunch on weekdays at Plaza Asturias or splash out on the pulpo a la gallega (a traditional Galician octopus dish) at nearby Restaurante El Globo, which is more than 100 years old.
