Absolutely amazing! Haven't had a croissant like that since Paris. The star ingredients are amplified by the rich buttery flakiness of the outer pastry which melts in your mouth with every bite. Strongly recommend the beef roast mushroom, it's insanely good.
We've tried every dessert they have to offer and each was worth every penny. There is great balance in texture and flavour. None are overwhelmingly sweet so you really taste the mango, chestnut, black currant, pistachio flavour of whatever it is you're trying! Be forewarned if you are lactose intolerant, every dessert uses cream but take a pill or man it out; it is really worth it! Personal faves are the Pisatache, St. Honore and the Rhum.
Truly a gem outside of the downtown Toronto core. We've only discovered Duo about a month ago and we've been a solid patron since!
