[Epitaph]

Ok. No I don't think it was Soy-sauce, the taste was not the same. I think it was some kind of oyster-sauce but i'm not sure. It comes with every quick-noodle package that you can buy at Lawsons or 7eleven or other kind of quickmeal-joint.
The sauce looked like soysauce and you really drowned the noodles with it and mixed with wasabi.
