The reason I give a 4-star it's because the place is cute, cozy, where you can purchase a drink and play boardgames with friends and they wouldn't care.
In turns of the quality of the actually bubble tea, they are very average. Sometimes the tapioca gets really soft but they still serve it, another complain I have is that their drinks are in general sweeter than the other bubble tea shops. I ordered a slightly sweet (25% sugar) and it still can taste very sweet.
Over all, it's a good place to chill and talk to friends. If you're only looking for good bubble teas, this is not the place. - BUT, at Yonge and Eglinton, this is the only bubble tea place in the area, so you don't really get a choice.
