Had my first experience with their products years ago, with a gift given to our family.
It's been a while since I've visited Toronto, but two trips to Chinatown this trip landed me at Ten Ren for bubble tea.
Went to the drink counter to the right, inside the front door.
So many choices, so I wasn't ready to order right away. Staff were very patient, and answered questions of certain drinks on the menu. Ended up getting the same drink as my friend (got an orange/mango bubble tea).
Drink was on the strong side (the way I like it), and perfectly sweetened.
One of the few places in town that I MUST visit when I'm in Toronto.
Before I forget, the place appears immaculate, and is very well stocked with all sorts of good quality teas and related products.
