Too Much Coffee

I've scoured the Internet looking for a recipe for Viennese Coffee. There seem to be a lot of variations. This being a European-based forum, I thought this might be a good place to ask--maybe even get a recipe from someone in Vienna (of course, I'm assuming it has something to do with Austria and not one of those misnamed things). Plus, I'd rather get a recipe from a Barista than from a cooking website, as one is more likely to focus on the quality of the original drink while the other on convenience.

It might not be easy for me to get all of the ingredients, but please list what you use, and I'll try to come up with alternatives if I need to.

I was planning on using French press coffee. Any suggestions for what kind/style of chocolate to use?

Thanks
