worth a trip if you're in toronto. the architecture is beautiful. the stores are pretty much what you will find at any other mall in the GTA-- gap, old navy, h&m, starbucks, etc. eaton centre happens to be very convenient and a very nice place to hang out in the winter, but it does get very crowded and loud. it's so big there are two food courts, although most of the options are just duplicated (hey, i won't argue with having two kernel's in one mall)
when i first moved here i was infatuated with eaton centre because it was so novel to have a shopping mall as a city centre. i've gotten sort of fed up with it though, since the prices haven't come down with the rise of the dollar and the stores are very very generic. i don't even bother going here anymore-- i'd rather hold off shopping until i'm on the other side of the border.
