Fnac - a shop for those who like CD's, TV's, Video Games, Anime, DVD's, Cameras, Books, Gadgets,…read morePhones..... to be honest, anything to do with Technology with the odd Book and Concert Ticket thrown in.
Yes Fnac is the Swiss equivalent of Best Buy in the US and boy, it sure does a good job. Any time I've had to make a big technical purchase (Tv, Laptop.... batteries) I've always gone to Fnac. They are helpful, friendly and will get you the right product and not try to screw you over either.
If you are a non french speaker, most of the staff also speak english... but come on, the only way to learn is to try ;)
