Bang bang there goes your heart (into cardiac arrest from the overconsumption of sugar). If you follow any Toronto food instagrams, you've probably seen the ice cream treats from here. They have Hong Kong egg waffles, cookies, pastry puffs, and now cinnamon buns as ice cream vessels. The waffles are made to order, so be patient if you're ordering this. I personally prefer the cinnamon bun to the waffles and cookies, but the icing on the bun makes the ice cream combo a little too sweet. As for the ice cream, they have an abundance of flavours. The vegan chocolate sorbet is rich and smooth, but my go-to flavours are totaro (coconut taro) and avocado. You can also sample when you're there but I believe they limit the samples when during peak hours.
Definitely a great spot to visit after dinner. There's a ton of fantastic restaurants nearby. Or better yet, come at an off hour to avoid lining up.
