I live in Scarborough so this is the mall that I grew up going to. Maybe I'm biased because of that, but I have no idea why people call it ghetto. Oh wait, I forgot...everything in Scarborough is ghetto, right? :p
That being said, maybe it wasn't always a great mall but recently/over the past few years, they've changed the mall a lot. It's gone through major renovations and tons of new stores have opened up that I would have normally had to go to a different mall to find...come September I won't even have to go to Fairview mall for a Forever 21, because it's opening in STC!
The store selection is great, I frequent the Coles, Walmart, H&M, Fairweather, and Bath and Body Works on every visit. The theatre is good. The food court has a wide selection. Like other reviewers said, the only problem is rowdy school kids, but if you go in the morning, or before 3, it's a great shopping experience. Nice and peaceful.
Another great thing about this mall is whats located around it. Awesome selection of restaurants and a huge Canadian Superstore.
Honestly, more often than not, I choose this mall over the Eaton Centre and Yorkdale, which are way too big for my tastes. I find everything I need here. In my opinion, this mall is very underrated.
