oops, forgot to update this thread with the report. We went to visit both the cheese factory and the chocolate factory mentioned further up this thread.
I can report that both places were English-friendly.
The cheese factory had one of those audio guides where you walk around and listen to information at certain points. They give you a little sample pack of cheese that you can take home. The tour consisted of info boards surrounding the factory below. The factory itself was tiny, so don't expect anything that will blow your mind. Fun way to blow 30 minutes.
Chocolate factory was a bit more tour orientated. You walk through various corridors with some history, pictures etc. There are videos to explain how the chocolate is made, and some staff at various points to explain some of the processes. At the end you go to a tasting room where all their products are laid out. My mother spent far too much time "sampling" at this point. Right at the end you get to see the factory itself (also tiny) through a glass window. Then of course out via the shop where you can buy the chocolate.
Great countryside around there, so I can recommend doing both of these things as they are also cheap and close together!
kryz, I take it you didn't mean to insult your girlfriend's family, and do mean that they are a bunch of goat farmers in the literal sense
