Nothing new to add here but I can affirm:
It is completely worth booking an appointment with Ayala. She is very creative, knowledgeable and has fantastic scents. And a really nice person. You will learn so much!
Perfume Shoppe is an incredible niche shop, one of the best I've seen anywhere. Naz is a very gracious lady.
The Holts flagship stores (Vancouver, also Toronto and Montreal I think) carry complete Creed, Frederic Malle, Etat Libre d'Orage, Acqua di Parma, Bois 1920, Carthusia, Kilian and other interesting scents at pretty good prices.
