I have really fond memories of eating Korean shaved ice when I was in Seoul. I had tried binsu in Seoul around 6 times at different places. And I'm happy to say that Soul Cafe is the closest you will get to an authentic Korean Shaved Ice experience within Toronto, or probably the whole Canada.
In Korea, Sulbing is probably the most well known shaved ice brand. There's also Mealtop, and some lesser cafes. Injeolmi (soy bean powder) is all the rage these days so I recommend that first. Comes with soybean powder, condensed milk, small pieces of rice cake. Coffee is another popular flavor in Korea. Red Bean is the traditional one (patbingsu).
Anyways, compared to Korea I actually don't find Soul Cafe expensive at all. One of the places I tried in Korea was called Artisee. They charge $15 (15000W) for a 2 people portion. Sulbing charges you over $10 for 2 people portion depending on the type. The cheapest I had was at a university fair for $4 for single portion. Surely $6.99 for a single portion is not outrageous to get an authentic taste of Korea. Quite reasonable!
Most surprising was that they do take out in a styrofoam cup.
I don't really have any comments on their other menu offerings. There doesn't appear to be anything special. The cafe itself is alright. Not the most upscale cafe out there. And thankfully not as flamboyantly girlish as Cafe Princess near Finch.
