I am okay with pickled, not a fan of raw.
But herring isn't really a national dish. Just something some people eat from time to time. It is not a staple in restaurants. If you want herring you get it at the market, maybe a fish monger.
We don't really have cuisine like the French, Italian, etc. got. We have some snacks and candy, but not something to open a restaurant with.
That is why if Epcot ever adds a new land, adding the Netherlands would not be a good idea. We also do not really have a style of music or entertainment that is particularly Dutch. (Except after this year everyone who is into Eurovision, knows our style

)
