I will always choose Coco's over Chatime. Just something about the milk tea that tastes better than other bubble tea shops. Prices are standard, a small cup with a topping will cost around $5. You also have the option to modify the amount of ice and sugar in your drink.
I can get the milk tea here without any sugar and it'll still taste great. The tapioca is bouncy and is never under or over cooked.
They accept vincinty cards here so make sure you bring yours or sign up for one to get free drinks!
There's also some seating available inside, but it's not particularly pleasant in the winter months since it's cold from people walking in and all the snow/slush from outside melts into a watery mess.
