Located Westbound towards Ossington and Queen, very far from the tourist trap that is Sweet Jesus.
This is hands down my favourite ice cream place in all Toronto.
Most likely when you go you'll encounter a line (even in the winter time) but it is very much worth the wait.
Bang Bang has an assortment of flavours to choose from and a few ways to enjoy them. Two scoops will set you back roughly ~ $7-8 but it is definitely worth it.
Their ice cream is home-made and it shows in the quality. Every bite is a wonder. My go-to flavours are: Totaro (Taro), Rocky Roadkill, and Mud.
You can have their ice cream in three ways: a bowl, sandwiched between a cookie, or in a waffle cone.
I've tried the ice cream sandwiches and I suggest splitting or eating half as they are definitely filling. I actually much prefer the HK Waffle (aka Bubble Waffle to some) but it may take a while due to popularity so take that into account if you don't like waiting too much.
If you're looking for some quality ice cream and don't mind making a trek away from the core then Bang Bang is what you're looking for!
The only downside I can think of is the typical Toronto line.
