The Finns are crazy about coffee, which is odd, when you come to think about it: the coffee beans themselves grow quite a way away. You will rapidly get used to the fact that when Finns get together for a chat, coffee is invariably part of the scene. But note that the coffee in Finland is usually not as strong as in Central and Southern Europe.
Together with the coffee, the custom is to take a piece of pulla/bulla, which is something between bread and cake, slightly sweet, traditionally baked at home.
You will also notice that in the countryside the Finnish institution known as a bar (baari/bar) is not always a bar in the international sense, but more like a café. Finnish bars serve simple meals washed down with a light beer, or coffee and pulla and the like.
Except coffee, Finns are also crazy about alcohol ...you can notice this especially after dark :)
