The traditional culinary specialities are always worth bringing home with you, and to find these in Oulu you only need to know the way to Kauppahalli, the Market hall by the sea shore next to the market place. In Kauppahalli you can find for instance salmon and reindeer prepared in different ways, famous Finnish bread and arctic berries. Not far from the Market hall you can also find a number of traditional old warehouses still smelling of tar, the Finnish gold. These warehouses offer interesting Lappish products at reasonable prices.
