First of all, you have to know (and appreciate) what you're getting into.
Legit Sichuan food is actually tough to come by in Toronto. It's fresh, it's spciy and it cuts right to the chase.
Outside of Markham, most Sichuan restaurants I've been to have been dives. So while SS may not be setting the design world on fire, it's clean, modern and totally serviceable. Really, all I'm telling you is that decor is a non-issue. The food is what we care about.
You want it spicy? Good. Traditional dishes, such as Sichuan jelly and water cooked beef go a long way. There are a few options in there for people who are used to traditional Cantonese food (and even Northern food, such as lamb skewers).
My advice is to go, order a bunch of dishes to spare, wash it down with some Tsingtao beer and enjoy the ride. I've been happy and totally satisfied every time I've gone.
P.S. I last went just after Christmas but noticed a review that said it was now closed. I'm going to hope that it wasn't suffocated by the surrounding restaurants because 1) these guys were doing a good job; and 2) I don't want to drive to Markham just to get chili beef done right. :(
