I've been to a few of the other Chatime locations across the GTA many times and for the most part, the experience has been consistent and worth it. Yes, the lineups can be legendary but hey, you're either there with a friend or your smartphone so lineups can be bearable now.
The issue with this Chatime is their roasted milk tea is lacking the roasted flavour that you've come to expect after visiting the other locations. I've been to this location now 4 times since it's opened and each subsequent visit leaves me less and less confident it was a one-off situation.
The other issue is their early closing time on weekends for a bbt shop. They close at midnight - which isn't too bad but the crowd that goes out for bbt on weekends, I bet the majority of them want to stay out later than midnight. If your other locations can close at 2 am, why can't this one? Hopefully this is something they'll look into and change in the near future.
