Buenos Aires, best known as the Paris of South America for its vibrant culture and architecture, has become a major tourism destination. And there’s plenty of interest for the Jewish tourist. Argentina has one of the largest Jewish communities in the world, and the largest in Latin America, with estimates ranging from 175,000 to 250,000. The neighborhoods of Once and Abasto, in the heart of the city, are full of synagogues and are the main area for kosher grocers, butchers and restaurants as well as Judaica and Hebrew book stores, largely clustered on Calle Tucuman. In years past, the neighborhood contained a mix of Ashkenazi, Sephardic and Mizrahi Jews, but today, Sephardic and Mizrahi Jews remain the most visible. Many Ahskenazis have assimilated, spreading into the suburbs.
