Btw. it is "das Frühstück" as well.

But you get laughed at when saying "das Cola" in Germany, but yelled at being a stupid German when saying "die Cola" in Vienna. Which makes the whole thing great, because it obviously annoys us a lot, both is correct though, and it totally doesn't make a difference what the gender of the thing is :)

We have lot's of words where the "Duden", the official dictionary has an "Austrian also: ..." alternative gender. And then there are colloquial habits that are utterly out of spec which make me furious to be honest. Who the hell thinks "das Teller" sounds right?!
