In Austria (well, at least in Vienna) it is realatively easy to find Sriracha, but I haven't found a store that carries Huy Fung yet. The main brand in most stores is called Flying Goose, or something to that affect. It is noticeably sweeter (I think there is more sugar) and less spicy than Huy Fung. It is a bit tangier as well. I do hope to find the Huy Fung brand eventually, if I can!
