Reindeer food receipts are good in Norway, for example, but the restaurants offering them are very hard to find. Usually, restaurants offering local Norwegian food are not easy to find, most of restaurants offering either Italian cuisine such as pasta and pizza (there are even jokes about a very often found pizza mark, "Grandiosa" as being now a national Norwegian receipt
), fast-food-like cuisine, or International cuisine.
Smoked salmon fish is also good.
Concerning sweet things, nothing is better than the Swedish cakes, with or without cream.
