Nah. Beef (hi-class stuff) is actually a bit less expensive than real quality fish. Of course, all foods are much more expensive than in the US - I think if you made a bulk comparison you’d end up with US prices at around 30% of Norwegian.
Of course, the way Obama is going, he may have the US more comparable to Europe (or Egypt) real soon.
The Swedes say food is so expensive in Norway that they sell half cucumbers. And food in Sweden isn’t cheap by any stretch.
