Definitely worth for the instagram pic haha. I came here when visiting Toronto this past weekend. We came on a hot sunny day, and there was not too much of a lineup.
The service is fast and friendly and the ice cream consistently looks as aesthetically pleasing as every pic you've seen of it on Instagram. The portion size is also huge- you get a lot of ice cream so the price doesn't hurt as much.
I'd give the actual ice cream a 3.5, only because it melts SO fast. I got the ube nut (purple and black swirl), and by the end, it was dripping all over me. As others have mentioned, they put a marshmallow at the bottom of the cone to help prevent drippage from the bottom but it doesn't work at all LOL. It was a disaster by the time I got to the bottom!!!
Overall, I'd definitely recommend. I liked the flavour of the ice cream; it's not strong, but I liked the subtle flavour.
