Lima is known as the ''Gastronomical Capital of the Americas''. A center of immigration and the center of the Spanish Viceroyalty, chefs incorporated dishes brought by the conquistadors and waves of immigrants: African, European, Chinese and Japanese. Since the second half of the 20th century, international immigrants were joined by internal migrants from rural areas. Lima cuisines include Creole food, Chifas, Cebicherias and Pollerias.
