I first tried CoCo tea at their Scarborough location because of a recommendation from a friend and I'm glad I did. It was added to my ever-growing list of bbt places to go. When we found out there was a Mississauga location, we had to try it as well. As of today, I've been to 3 different locations and it's safe to say, they are consistent with their bbt across all.
Drinks: I've tried many different options on the menu and haven't had a bad drink yet. I will mention that their drinks are sweeter than others so I lessen my sugar to either 30% or 0% depending on which topping I go for. The Sago has to be one of my favourite toppings and I haven't found it at any other bbt place yet. They soak it in sugar so it's best to get 0% sugar if you're getting it. I'm more of a Jelly and Pudding kind of gal but I can enjoy their tapioca once in a while as well. It's not too soft or too hard. I would compare it to Chatime's tapioca.
The milk tea is a nice balance of tea vs. milk for my taste. You get more of the tea flavour and it isn't overpowered by milk. Their juices and fruit teas are also strong in flavour (in a good way) but I would recommend less sugar or none.
Interior: This location is pretty small and only has a few tables. It's brightly lit though and very clean (it is new afterall). They can fit maybe 15 people or less so if you're looking to hang out with a large group of friends, take the drinks to someone's house. It's more of a take-out location.
