An article about Finnish cuisine exists. Because as a concept, we can talk about it.
But in the sense of there being restaurants for it, like Italian, Mexican, Greek, Indian, Chinese, etc cuisines, I would bet quite a lot that you can't find one single restaurant dedicated to "Finnish cuisine" outside of Finland.
It's just that that's not how cuisine is usually understood. But like I said, I wasn't trying to change your opinion, just noted that as usually defined it does exist.
I don't know if you think the colloquial use aligns more with what you said, but in Finnish cuisine is just "keittiö" (as in suomalainen keittiö) or ruokakulttuuri. English word is much the same in that it actually doesn't just mean something fancy, even though as a French origin word it can seem like a fancy word.
I'm just going with that. It's not a personal preference thing. I like Finnish food but it doesn't really matter to me if the term cuisine was reserved for just fancy. I was just saying.
It's about the concept of a "cuisine". I'm sure you understand what is meant by it.
I don't believe there are any "Finnish restaurants". There are restaurants which say they serve traditional food, in Finland, sure. But I'm quite sure no other country has a "Finnish restaurant" and that literally no-one ever has asked their friend "hey d'you wanna go out for some Finnish?"
You can like the food, I'm not trying to make you enjoy something less. I'm pointing out Finland lacks food culture, as sorely as it lacks other forms of culture.
