Customs

Buenos Aires has always been an open-door city. Its inhabitants are called porte�os, which makes reference to the fact that the city is a port. The inhabitant of the province of Buenos Aires is called bonaerense.
Porte�os are warm and hospitable: they usually invite tourists for lunch or dinner at their homes and prepare typical food.
The characteristic infusion is the mate. It is prepared by pouring warm water into a gourd, also called mate that contains yerba mate.
Some people add sugar, but most prefer 'un amargo' (a mate without sugar)."
