I'm based out of NYC, but when I'm in Toronto, I always come by here. (I love to grab lunch or dinner at one of the many restaurants in the plaza, and grab an amazing drink on my way in or out.)
Location is incredibly clean. Parking is very convenient (lots of spots in the front and back of the plaza, along with a parking garage). The staff are very friendly and helpful. I always find the quality of the drinks done consistently well. My personal favourites are the hot roasted milk tea with grass jelly or the mango qq.
I never come by this plaza without dropping by Chatime.
