Scandinavian food is great.
It seems the most disgusting foods people could only ever eat out of necessity are the ones that never catch on in other areas, and therefore remain local "delicacies". Their disgustingness in turn means that even the people who came up it will only ever touch it once a year, making it even more of a "delicacy". The result, people think they're obliged to eat nasty things like "lutefisk" when they visit (or, if you're a 3rd generation Minnesotan, that it connects you to the 'old country' and must be eaten once a week), which is unlikely to leave a good impression.
Between the bland British-like food and the disgusting delicacies, there is some surprisingly tasty stuff. Not comparable to Greek cuisine, of course, (though it wouldn't kill you guys to cut back on the lemon and spinach) but not as abominable as one might think.
Scandinavian sweets, on the other hand, no competition. At least not outside the Germanic world.
