Duo continues to be my favourite patisserie in the GTA area for several reasons:
1. There's nothing on the food menu that I don't like. This is coming from someone who's tried every single one of their viennoiseries and cakes: everything is impeccable.
2. The atmosphere is laid back, and service is always very polite and friendly.
Price-wise, it's pretty consistent with what you'd find elsewhere for patisseries like Nadège or Butter Avenue.
Be sure to get there early because their cakes often sell out well before closing time.
Recommend: Nova, St. Honore Cassis, Matcha book, Apple croissant.
