I've been here only once and I definitely would return. If only I lived in Richmond hill!
We came here on a Saturday afternoon to grab some bbts to go. The store is cute and unique, I love that rustic feel to it, as well as the cute little drawings of the tapiocas on the wall. Unfortunately the store is tiny and can't really seat too many people. Therefore I would recommend going with a small group (i.e. By yourself or with just one other friend). Customer service was good, they introduced us to their tea leaves and let us sniff a couple of them. This is the first bubble tea place where I'm 100% confident that they use real tea. In addition, they make their own tapioca from scratch.
In terms of their tea, I ordered the iron goddess milk tea. The taste of the tea was rich (might be because I just saw their tea leaves and it's just a placebo effect?) and the milk wasn't overly sweetened. All tapiocas taste the same to me so I can't really comment on them.
My friends ordered the royal no.9 milk tea. It really wasn't my cup of tea. I don't quite get the appeal of adding milk to fruit flavored tea, but since it's so popular, there must be something good about it.
The price of the bbts are on par with chatime's / goncha's. Who are we kidding, good bbts are all expensive.
