I love this Starbucks! Right on Yonge but not packed with people. The service was really friendly, and there was no line when I was there.
Just comparing this to other Starbucks. The atmosphere was nice for a Starbucks in an office building, and I love how they tucked tables in every nook and cranny. I felt relatively isolated from the rest of the tables and it was great for studying. Also right next to an outlet.
