Know of any Shops in Paris?

Ok, so I'm going with my girlfriend to Paris on Friday for the weekend. The thing is, we were looking to pick up a couple of bits and pieces and don't have time to do it this side of the Channel. Anyone know of any shops near the Windsor Hotel Opera? Address is 10 Rue Gabriel Laumain Paris 75010. Obviously don't want any really grotty ones, something like Ann Summers?
