The term el centro is confusing: although people tend to say "Voy al centro" or "Trabajo en el centro" (without the capitals), meaning "I'm going downtown" or "I work downtown," they're using the term generally. The official barrio names of the downtown area are San Nicolás and Monserrat, though few people use these either. Suffice to say that "el centro" is really an umbrella term to cover several action-packed districts at the city's heart. In it are theaters, bars, cafés, bookstores, and the crowded streets you'd expect to find in any major city center.
