Boulangerie Guillaume is widely praised for its bread and pastries, with many calling it the best bakery in Montreal. The bread is described as excellent and the croissants and other viennoiseries are often highlighted as standout. Service is consistently friendly and attentive, even when the shop is busy. Several notes mention practical drawbacks such as the absence of a bread slicer, small bags, and occasional price increases or changes after a move to a nearby location. Space for eating on site is limited and some reviewers wish for sturdier reusable bags and more eco friendly packaging. A few patrons mention a dog friendly policy and overall the place remains a go to for fresh and flavorful breads and pastries. Overall the reviews depict a bakery that delivers high quality and variety, with some caveats about pricing, slicing, and space.
Camping ain't camping with good bread.
The Pullman from Guillaume is the only bread I'd bring on a multi-day trip. Perfect as toast, grilled cheese & french toast.
Ohhh & the White Chocolate Mushroom, I'll leave them to speak for themselves.
The unfortunate thing is I was actually most excited about this place when visiting MTL. I heard such great things from a friend & I walked over 30 mins to find it. This is sadly an example of more is less, & overproduction = lower quality. The pastries feel very subpar & bland. Almost as if they are making enough to feed the abundance of people coming into the shop but not taking the time to do anything special. I was unfortunately let down by this but they do have a blueberry tart that was a silver lining in all of this

This was so good! Friendly, attentive service. The croissant au fromage may be the best I've had in the city. The feuilleté suisse was incredibly fresh. 10/10 I will be coming back.
I've heard a lot about this famous bakery, so I tried baguette & chocolatine. The baguette was a little gummy, in general, nothing remarkable. The chocolatine was not a good experience, it didn't taste fresh, it was not crispy, it felt dry & the chocolate didn't taste good. The service is acceptable. Not coming back.
I tried the mushroom cake, the regular croissant, & I think it was called the Elizabeth something cake (sorry if I don't recall correctly). The mushroom cake had a crunchy topping with a coconut flavour, which I'm not usually a fan of, but I really liked the regular croissant. It had layers of creamy flavour & smelled great. The mushroom cake was just okay, to be honest.
Amazing selection of breads & other baked goodies! They have almost everything you can think of, from the classic pastries & breads to some remarkably innovative combinations. I was incredibly tempted by everything in the display case -- especially since the bakery smells like butter & sugar -- but eventually settled on their white chocolate brioche. The chocolate is mixed into the batter to give the entire roll a slightly sweet flavor, which is delightful when paired with the already soft, pillowy, & buttery brioche. I can't wait to go back & try more of their selection!
Connaissant l'endroit depuis quelques temps maintenant, je suis assez déçue. Il m'est arrivé d'avoir des morceaux de pommes de terre pas assez cuits dans le pain fesse-patate-cheddar. Le pain est assez blanc & goûte rance. Les sandwichs coûtent presque 10$ & ont peu de garnitures. Il n'y a pas de trancheuse non plus. Sans compter les groupes de touristes avec guide qui viennent polluer la boutique, je n'y retourne plus.

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! 🍞💛
Excellente boulangerie. Le service est toujours courtois malgré l'achalandage. Quand on aime vraiment quelque chose. C'est bien d'appeler & on réserve à votre nom. Très pratique!
Beaucoup de choix & une belle sélection côté épicerie. Reste que dans l'ensemble, les viennoiseries manquent de moelleux & sont plutôt sèches, ce qui me donne l'impression qu'elles puissent être de la veille. De plus, j'ai acheté des pains à burger & leur taille n'est pas uniforme : je me serais attendue à ce qu'on me précise que certains d'entre eux étaient tout petits, avant de m'en apercevoir une fois chez moi...
Cheese croissant is just amazing here, white chocolate & vanilla mushroom too. They even have many types of sourdough & everything is freshly baked. Their olive ciabatta bread is just delicious. I visited the place many times & I got a very good service from the staff. I would really appreciate it. They recently released a new thing called browkie I guess brownie+cookie which is interesting. I definitely recommend this place if you love traditional sourdough & baguette.
Leurs produits sont très bons, mais c'est la première boulangerie que je vois sans trancheuse, ce qui est particulièrement gênant. Pour ma part, c'est typiquement le genre de détail qui me pousse à aller ailleurs.
