By far, my favourite place for a cappuccino on Queen. While I haven't tried anything else, the caps have been consistently good (Smooth, creamy, aromatic) and their sammiches look yummy!
I found the caps at T.A.N too milky, and the espresso at White Squirrel and Second Cup were burnt from being held in the machine too long. (Boo Hiss)
The atmosphere is pretty decent in terms of getting work done. I'm usually around in the mornings and afternoons on a weekday, and there is plenty of seating an electrical outlets. It's bright, clean and airy :)
