I have tried cookies sold at fou d'ici on de maisonneuve w (place des arts metro): they were all good (chocolate, lemon & ginger, dark chocolate and maple), except for the chai latte one which had a very strong, funky taste and smell.
I am still eyeing the Reine Elizabeth cake, as well as the carrot cake!
Definitely worth a visit if you are on a gluten-free diet and want to treat yourself to a guilt-free dessert :D
