This Cha Time probably has the least amount of lines out of all the other ones I have been to. They are also one of the few ones that actually have seating for their customers that isn't constantly packed full.
I come here with my gf after dimsum sometimes and she usually gets the #2 with 50% sugar. I myself enjoy the many slush options, but often go with the staple taro smoothie as it is simple and always tastes great. Don't forget to choose your sweetness amount as this is one of the few bubble tea shops in the GTA that offer custom sugar sweetness options.
The service is what you would expect, but they do cut through the lines rather quickly. I will definitely come back next time I have a bubble tea craving.
