One of the many bubble tea stalls inside of First Markham Place. They may have even been here when the mall first opened, since I've always remembered them being there (although they did move their stall a couple units over).
I've been a regular here since a couple years ago (6+). Having been open for so long is a testament itself to the quality of their service and drinks!
For only $2 you can get a regular sized drink with a wide assortment of flavours. They also offer a stamp card so every 10th drink is free.
Of course there are much better quality drinks that can be found in stand alone bubble tea shops, but this place offers the best bang for your buck!
