Probably one of my favourite malls of all time. It's literally open almost every holiday when other malls aren't and they've got so many stores to choose from, especially with all the renovations from the closure of Sears. I'd say there's definitely more high-end stores than there are affordable ones so that's good to keep in mind for budgeting purposes. It's in a great area--the heart or downtown Toronto and across the street from Dundas Square, the Atrium, and is alongside many restaurants. It's also great in the summer time as there are many street festivals in the area. I also like that there a bridge connecting the mall to The Bay, especially during the winter when it's really cold outside. The food court has also been renovated just like what they seem to be doing with every other mall in Toronto.
Eatons is always super crowded and is a spot a lot of tourists like to go to due to its location. To avoid the crowds, its best to go earlier during the week at non-peak hours.
Even if you can't find something in the mall (which probably highly unlikely) there are many other stores in the area to choose from.
