I'm going to my faovrite restaurant in Oslo -
http://www.brasseriefrance.no/
the "beef tartar" is to die for - and they have snails mmmmmm
...I must admit I have made a name for myself there because I ordered the large beef tartar for desert and my little brother ordered 500g of Moules maison sauce crème et safran

- It's actually a good way of beeing remembered positivly in a restaurant without giving an extreme big tip - Just order something unexpected for desert hehe
