Came here as part of a food tour & my only disappointment was we couldn't buy more foods to sample (without taking arms full of breads & pastries home!). We ended up ordering some items to our Airbnb before we left Montreal this morning because our food tour ended late & we couldn't go back to purchase anything else!

What we did eat on the tour was delicious though! The Champignon chocolate blanc & vanille was absolutely divine. Would absolutely recommend getting one if you are nearby & also trying a few other things. Please be advised the bakery has moved just down the street but it's well posted on the old building :)

We will definitely be back next time we are in Montreal!

One of my favorites bakeries in Montreal & probably of all the Mile End neighborhood. Every single of their baked goods are fresh, prepared with love, generous & very tasty. The champignon is their most famous seller but I have a soft spot for their chocolate chip cookie & lemon cake. I haven't tried everything but there's always a good excuse to come back.

Best bakery in Montréal hands down! 🥖✨
Boulangerie Guillaume never disappoints. I picked up the pain brioché & the miche de levain both absolutely divine! The champignon à la vanille & the pralinée pastries were next-level delicious, such unique flavors done perfectly. Also grabbed the pain fesse au fromage… SO good, cheesy, fluffy, just wow. Everything is fresh, flavorful, & made with so much love. A must-visit for any foodie in the city!

Meilleure boulangerie de Montréal, sans hésiter! 🍞💛

Super expérience chez Guillaume !! Le fameux champignon qui a mené à son public fidèle & de s'agrandîr depuis son ouverture il y a 12 ans. Donc le champignon, Hyper moelleux avec un goût Tellement délicieux !! On a pris des petits « fesses » cheddar/patates & fromage/herbes! INCROYABLES!!!!!! La service vraiment chouette ! Le seul hic peut être c'est que nous ne voyons pas très bien les viennoiseries qui sont derrière la caisses ( & il y a du choix !!) Franchement super rapport qualité prix, ça vaut vraiment le détour 😎😎

I miss your torchon choco-orange. Please bring it back💔

Edit: but otherwise, I love this bakery with all my heart! The croissant, champignon, bread are all regular purchases. I carry around my Guillaume tote bag everywhere I go. I’m so glad Guillaume exists!
