My asian compadres set me onto this hidden gem on Dundas street. We've been here around 3-4 times together. The drinks are good, they have a good variety, and you can choose how much sugar to add and what stuff to mix into the drink. Some of the best bubble tea I've had in town. I like the smoothies they have there and the drinks are priced on par with other similar shops. They also have some bizarre quotes on the wall, which I enjoy.
The downside is that the shop is small, has limited seating and is always very busy right up until they close and kick everyone out. I've never been in there when there has been less than 10 people in front of me in line and no more than one table free.
