I don't think we have one.
Rio de Janeiro has several popular dishes and I don't think you can name one, but one that is very popular is "beef with fried potatoes", which is usually served as beef + fried potatoes + rice + bean + farofa + salad.
There are quite a few popular, regional and national dishes:
Out of those, I believe the only one I know is Polenta. I like it. I didn't know it was popular in Switzerland. :)
Polenta is not uncommon in Brazil, and we call it "angu", or sometimes "fubá" (actually, "fubá" is the name of the flour used to make it - it's a flour made out of corn - but we sometimes use this name for the dish).
We also have "pamonha", which is very similar.
Lol, Primeiro - that looks good indeed.
Here's some info about the "Polenta":
Mämmi? I doubt that would do... Then again...
In our area it's pork and sauerkraut. You get used to it and then you really like it.
Toss up between Tex-Mex and BBQ here in Texas.
