I've been to this location a few times since they've opened. Super convenient location right at Yonge and College intersection and not as busy as the Chatime on Dundas.
I have found the menu and drinks I've received to be made pretty consistently. The space is also nice and spacious. There are usually several tables open. The staff is also super friendly.
However, each time that I've gone, they've been progressively getting busier and busier, but the number of staff does not seem to have changed. Currently, I would expect a 15-20 minute, which isn't too bad compared to other Chatimes. I hope they continue to expand to meet up with the demand.
