Lutefisk is still fairly popular as a traditional meal around Christmas here. My family always eats it on, ehm, Little Christmas Eve, but I find it fairly gross so I stick to the standard rice porridge with a hidden almond. I think Norwegian cuisine is pretty affected by the fact that we got very rich fairly fast, so a lot of the traditional stuff is influenced by much poorer times, but it's still tradition, so it's not likely to disappear any time soon, even though we are both richer and have influences from all over the world now.
