I've been to their Markham location but they are currently having a pop-up at the Adelaide Eats market so decided to give it a try. I ordered the activated charcoal soft serve and it was $5+tax. They also offer the soft serve with a stick of their signature wooffles and that was $6.50+tax. Overall it was not worth the $5 I spent; the soft serve did not taste like too much (vaguely tastes of vanilla) and the serving size was very small (the cups are the size of those you'd receive mouth wash in at the dentist's office).
