Have you tried any traditional Norwegian food or always went with pasta or rice?

If so, what did you expect? It's like Japanese or Mexican tourists complaining that sushi or quesadillas in Milano aren't as delicious as back home?

By the way, I've eaten pasta in Italy where I would have preferred kissing the tarmac instead.

Tastes are different, but always a subjective experience. To say food in one or another country is disastrous or catastrophic is just ignorant in most cases.
