CoCo is arguably Chatime's biggest competitor, as there seems to be one not too far away from where you are if you're in the GTA. While I'm a diehard Chatime fan, I decided to give CoCo a try since a friend I was with insists on CoCo over Chatime.
The place is quite small and can get quite crowded, especially when I was there on a Saturday night. The employees inside are efficient, fortunately, and I got my drink in less than 20 minutes.
I had the tapioca chocolate, with less ice and 50% sugar. It definitely felt like less ice and sugar, to the point where the chocolate taste was more "cocoa"-y, which I personally like better. While the prices are similar to Chatime, the sizes seem larger here, so you get more bang for your buck.
My parents have the Vicinity card for CoCo and have been diehard CoCo fans as well...so it's a good chance that I'll return (although I might try another CoCo branch).
