I'm not particularly into BBT and I only really drink it 3-4x a year. However, from all my BBT experiences in the Mississauga area, this one is definitely better than Chatime but does not have as many options as Bubble Republic. Cocotea is in the same plaza as the famous Emerald dimsum restaurant and parking can be difficult if you come near dimsum hours or on the weekend. The shop itself is small unfortunately, and there is limited seating. It gets really crowded when there's a long line up to order drinks, which makes it so chaotic. I don't really feel comfortable chatting/hanging out with my friends here though; the place is already small and with the bar and washroom close by, it gets super loud especially when there's some sort of blending action going on.
I have been here twice since they opened. I've tried the Yakult smoothie and the famous 3 Guys. Both were great and they made it according to my liking (zero sugar, regular ice). Feel free to customize it any way you like, the staff there is friendly. Follow them on social media (instagram/facebook) because they usually have a drink of the month for a discounted price!
Props that I get to collect Vicinity points.
