“Casa do Norte” in the Southeast of Brazil.

Casas do Norte (Houses of the North in English), are either restaurants, which serve food from the semi-arid, northeast region of Brazil, or stores that sell food, candy, drinks and other things from the Northeast. Sometimes they are both a restaurant and store, combined [in one]. The premises are always decorated with objects of North-eastern culture, such as hats, bottles, horns, etc…

They are very popular in the Brazilian Southeast, mainly in the states of Rio de Janeiro and São Paulo, because of the many types of food and drink which would otherwise be unavailable. There are a large number of north-eastern migrants who have arrived in the Southeast looking for work and they like to eat their customary food and keep in contact with their culture.

Some south-eastern natives also like to eat north-eastern food. Occasionally, I go to a “Casa do Norte” to eat. Some of the delicacies that can be found are - “Sarapatel, Buchada de Bode, Caldeirada, Baião de Dois” and various other dishes.
The most popular candy is “Rapadura” (candy made from sugar cane), but other candies and drinks, such as handmade “Cachaça” (an alcoholic beverage, made from sugar cane), is also available.
