I cannot say enough good things about Nordstrom. It is usually the first stop on my shopping route whenever I come to Fashion Square. Particularly on Boxing Day to check out their great shoe department! Especially their designer shoes - I've gotten amazing deals on Prada shoes - waaaaay better sales than Holt Renfrew as a tip for Canadian readers! Beautiful store with excellent customer service.
I have found some good pieces, but they tend to be workwear and not so much for casual. They have a great selection of my favourite designers for work attire - Elie Tahari and Hugo Boss in particular. For casual, I tend to check out Nordstrom Rack as there are good deals to be found there. I haven't found as many good sales in the clothing as I have in shoes (I love a bargain if you can't tell!).
Nordstrom's website is also a great place to hunt for bargains (their regular site, Nordstrom Rack and Hautelook). I like a few designers that are sometimes hard to find in Canada, so I tend to watch them online and wait for good sales. So happy they ship to the Great White North!
