As far as malls in Canada go, this one is top notch. It has a lot of selection in one place and a lot of great and unique places to eat. There is a good mix of high end stores (Ted Baker, Michael Kors, Coach) to inexpensive stores (Zara, H&M, Hollister).
The Good:
1. Selection. There really is something for everyone here. Eaton Centre boasts a lot of great stores.
2. Food. There are lots of places to eat and the places to sit are unique and quite comfortable.
The Bad:
1. Busy. This place is always super busy, especially on weekends. It's a hub for annoying tourists who don't understand universal escalator protocol.
2. Layout. The layout is not the best, especially now that Sears is gone and you can't stroll through there to get to Dundas street (you need to go down a level or two then go back up).
Recommendation: visit the mall on off hours and during the week. Your head will thank you!
