The shop is hidden amongst the construction in Union Station and is fairly new. It's located between the Go train terminal and the TTC station. I stumbled across this gem to find a line coming out of the door on Monday after work (around 5:30pm). I am told the line goes out the door and sometimes loops in the morning as well!! The line for me went quickly and the staff were very helpful.
I chose a cinnamon bun with a custard centre and chocolate topping ($3.10 after tax). The pastry was delicious and flakey and not doughy at all. This might've been the best cinnamon bun I've ever had in my life. The raspberry jam croissant was also delicious. They were not overly sweet and stuffed. Everything seemed to have the perfect balance - I'm drooling over how good the pastries were!
Even though I just had it yesterday, I wish I could go back and have more! I can't wait to return and try everything they have!
