This MAC store barely gets a passing grade if you compare it to every other counter in the city. If I'm nearby and desperately need to replenish something in my kit I'd rather walk two blocks east to the Bay store/Yonge subway kiosk or even hold off and go to the Pro store on Queen (http://www.yelp.ca/biz/mac-toronto-3#hrid:yrusFG4v79mqMFT-wjQFxQ).
Yes, they have almost all the same stock, but one thing in particular keeps me from coming here:
The staff.
Not only are they unwelcoming and gossipy, but I've never NOT had to interrupt a conversation between staff members to ask for something. God forbid you not know what you want and have to take up even more of their time. You're reminded that this is Yorkville and you are not exactly welcome here. No one is eager to help you. Also, compared to the other stores, the MAs here are very garishly made up. While I understand that MAC has a theatrical aspect to it, I usually come away with ideas or inspirations for future makeup looks - but never from Yorkville MAC.
