Enjoy authentic Italian dishes in South Australia restaurants. South Australia has had a substantial Italian migrant population for decades and the state is well-served for Italian restaurants. The highest concentration of Italian restaurants in South Australia is unsurprisingly in the state capital Adelaide. Adelaide's Italian-Australian community settled in the north-eastern suburbs of the city, including Campbelltown, Athelstone, and Rostrevor. These areas have plenty of traditional, family-run Italian restaurants offering home cooking. Italian cuisine has become such a popular dining option in South Australia that new restaurants are springing up regularly, many of them offering a contemporary take on traditional recipes.
