Just got back from a Paris trip where I visited this shop. Such a fun place and great atmosphere inside. Be prepared to wait as it can get busy in there and it can take some time for them to wind off your yarn once you've told them what you want. Knowing a bit of French (eg. I would like) helps but the staff is really friendly and I think used to getting non-French speakers so they work with it pretty well, just remember to smile and be polite. If you want buttons, you can get them in the same queue as for your yarn, just be sure to tell them you want some as well (be warned there are lots of lovely ones and you might walk out with some even if you don't plan to like i did!). The other items (beads, ribbons, etc.) you have to go to the other 'departments' to get seperately but if I understand right you can pay for it all in one go.
