Hermes Bakery. Wow. I dormed next door to it for a full year. Their kokosh cake is literally worth killing for, as are their cherry open faced danishes. There were literally times I ate 3 of them in a sitting!
That being said, their service is not the greatest, and there were two occasions that I had a foreign object in a baked goods (a toothpick and a pit) hence the four star rating. I definitely suggest you stop by there if youre in Toronto.
