I hit up this place every time I'm at Yorkdale. The Americano alone is divine, and they do interesting flavoured Latte's. The pastries and baked goods are very good too, and really high quality. There are one-stall bathrooms which are really great in an otherwise overcrowded mall. You can even get seating in the general mall area just outside, under a lovely glass ceiling.
Service is.. meh, though. They can't seem to operate the lines efficiently and I've met some pretty impatient cashiers. Also, they won't heat baked goods because they "don't have a toaster oven and are unable to provide this service." Guess I'll keep munching on my lukewarm scone (which is otherwise quite yummy) while imagining it can be so much more.
