Was just in Paris and visited most (all?) the Chanel stores. I was specifically looking for a bright colored mini and this other lizard bag I saw in NYC. Here's my finding:
Cambon - Nice stock (of everything but minis), did not like SA (snooty) and I felt like she didn't want to show me any bags, had to wait awhile to be helped
Rue Royale - nicest salespeople of all the stores but not great stock, had to wait awhile to be helped
Printemps - horrible experience - security guard said i had to wait in a line which no one was in. After a couple minutes I was getting annoyed as I just wanted to see what stock they had out. He begrudgingly let me in and nastily said "don't touch any of the bags". Meanwhile someone's child was running around with a boy bag. What an a-hole. I literally was like nevermind and left.
Galleries Lafayette - there was a line and I didn't want to wait (was already annoyed after printemps experience)
Bon Marche- the security guard ALMOST made me wait in a non-existent line again but he must have seen the look in my eyes lol. Nice salesperson. I find this store always has something I like because I feel like a lot of people don't visit it. Salesperson went out of his way to check something for me and also brought me something I liked (very rare since I'm so picky and SA's generally don't listen to what you are truly looking for).
St honore store - Nice salespeople and good stock of minis. I feel like they don't have that great of stock in other bags since its such a small store.
Montaigne (the one on the right side of the street as you're walking down) - BEST stock of minis and no wait for SA. However, I did not like the SA at all. Very unfriendly/snooty. I said I wanted to see what mini's they had and she showed me what was in the cabinet but I noticed once I walked around there were quite a few displayed which I wish she would have taken me to instead of just showing me the closet stock. I felt like I was annoying her with my presence and it made me very uncomfortable. I didn't end up buying anything but if I did I would have come back and asked for a different person. They had great stock of other items too. This has always been my favorite store.
Montaigne (left side of the street) - No wait, SA was OK but not really helpful. Just opened the cabinet and stood there while I looked then shut it really quick (?!?). Great selection of minis (not as good as the other montaigne store though). Generally this store is always crowded.
I also went to the store in Vienna - I asked if they had any minis and the SA said no even though I saw some displayed (not good colors though).
