I come here once a year every time I'm in Canada.
Everyone that I go with (teenagers, I'm the only adult lol) agrees with me when I say this place is amazing.
Off the top of my head there are:
DVD stores that will have tons and tons of movies, animes, dramas, etc for super cheap
Anime merchandise stores
Snack stores with candy, drinks, food etc.
Asian Fobby gyaru (?) type clothing stores (Their stuff is expensive! But just haggle with them, they're easy!)
Nail salons
Jewelry stores
A nice but really packed food court
Comments on personal things:
You can buy every fricking phone case in the world. My friend bought a life proof case for 18$ and it works. So much better that online even.
There's this one place in particular that we always visit. I can't remember the name but it's a DVD store that always does this deal where you buy 4 discs you get 1 free.
You can buy sets of DVD's for dramas, animes, movies, tv shows etc here.
For soooo cheap. I think most of the movies were about 5$ each. I in particular looked at the Miyazaki stuff. Those DVD's in America would have cost me 20$+ each.
We always end up getting a ton of stuff here.
