Osmo X Marusan is described as a visually striking, club‑like cafe that blends Japanese inspired sandos, curry bowls and drinks with a strong coffee and matcha scene, attracting a young, studious crowd and often becoming a lively, crowded space. The atmosphere is frequently praised for its architecture, skylights and terrace, sometimes with a DJ or vinyl vibe, but the overall level of noise and activity can make it hard to study or have a quiet meal. The menu features crowd favorites like tamago sando, karaage sando and katsu curry, with matcha and hojicha drinks earning consistent praise, though some reviews note small portions, bland elements or variable quality and long waits during peak times. Service quality ranges from friendly and attentive to slow or uneven, contributing to mixed overall impressions. Taken together, the place shines for its unique vibe, drinks and creative sandwiches and is often recommended for a social visit or a first experience, while not being ideal for those seeking a quiet, quick meal or a predictable cafe routine.
Les prix sont très chers par rapport aux maigres portions que mon amie & moi avons reçu. La musique est beaucoup trop forte à mon avis. De plus, la serveuse est venue nous voir 2 fois pour nous dire de changer de place puisque nous travaillions à une table'sans ordinateur'. Mais il devient difficile de trouver une autre place quand plus de la moitié du café a des tables'sans ordinateur'. Il y avait trop de monde & toutes les paces étaient prises, donc nous sommes allées nous refugier dans un autre café.
Un des mes cafés préfère à mtl. Really love the egg sandwich with or without salmon. I really recommend their chaï not a fan of matcha but looks like I should be.. 😂

Really loved this cafe. Super fun, youthful vibe - kind of like a school cafeteria during lunch, but way better.
Great variety of food, from healthy options to more indulgent stuff. Everything was delicious.
Would definitely come back.👍👍👍
Très bon café:) jaime beaucoup le dirth chai latté glacé!!
Bouffe simple mais de bons choix & savoureux.
À noter que c'est un café comptoir donc il n'y a pas de service aux tables.
Très belle place!!
OSMO has now become my favourite cafe in the city! There was good lowkey music, beautiful natural lighting through the sky light, & the food/drinks were top tier. I would recommend this place to go study or to go get coffee with a friend
We had heard about @osmo_x_marusan for years-whispered recommendations, glowing hype, forced influncer stories. A reputation that promises revelation. So when we finally went, our first thought was genuinely:'Did we even go to the right place?'
It quickly became clear that this is a café people come to experience, not necessarily to eat. The hipster-industrial aesthetic is immaculate, concrete, like you're going to a café in that club scene from'The Matrix.' It feels engineered more for Instagram stories & long study sessions than for anyone in pursuit of a truly satisfying meal. The space seems tailored to university students with laptops & deadlines, not diners with expectations.
The food, unfortunately, didn't rise to the myth. The tamago sando came with a strange, béchamel-adjacent sauce that felt both unnecessary & confusing. The karaage leaned heavily into grease without the payoff of crispness or depth, & the bread-for both sandwiches-was simply wrong, missing that soft, pillowy integrity you hope for. The yuzu lemonade? Perfectly fine-but unmistakably just lemonade, not even sure why they use the word'Yuzu.' Not even a faint taste of it.
Ironically, the most enjoyable part of the visit was the Osmo fog-visually delightful, theatrically effective, & perhaps the clearest expression of what this place does best.
We left full, yes, but not satisfied. At all.
@osmo_x_marusan is a café where the vibe works overtime, while the food quietly clocks out early. A place worth seeing once-but hard to crave again, once the fog clears.

Un de mes cafés préférés lors de mon passage à Montréal ! Avec une touche japonaise & très minimaliste, ce café propose une ambiance très rythmique avec des set DJ. On y mange très bien & le lieu est très adapté au co-working & aux échanges
Un très beau café au design unique, avec un menu d'inspiration japonaise qui se démarque. L'endroit est populaire auprès des étudiants, donc ce n'est pas l'adresse idéale si on cherche un moment calme.
Nous avons pris un matcha & un osmo fog, tous deux bien exécutés. Les sando étaient bons, mais manquaient un peu de saveur selon moi.
Malgré tout, l'expérience globale reste plaisante & je retournerai chez Osmo x Marusan sans hésiter.

It's a nice small cosy café in my Neighbourhood, which I have never seen before I discovered it because it's kind of like a hidden Café. I've tried their much with lavender, which was tasting good. Also, they had nice sandwiches. I haven't tried yet, but they looked very good. Maybe next time I will try that too.
The place is littered with laptops & people out overextend their stays. Choose your time wisely if you plan to visit this hidden gem. Feels more like a library with food than a great café with food.
Limited seating time would be a great suggestion for this place.
Absolutely loved my experience at OSMO X MARUSAN!! A friend & I visited MTL for a few days & had breakfast twice at this cafe. We got the matcha latte (hot & cold) & both were great. We tried two breakfast sandos: the tamago (8/10) & the katsu (9/10). There was a bit of a line up & waited after ordering but the atmosphere was great & staff were very kind so the wait was not bad. I would definitely make another visit during my next trip to MTL!
i got the tamago sando which looked better than it tasted. 😆 it was just mayo & salt, which was a bit plain for me. the flat white was also just okay.
the café was super busy even on a tuesday afternoon, probably because it's close to McGill, with lots of students on laptops. It was also pretty noisy, but the space itself was well designed & very aesthetically pleasing.
i grabbed a bag of coffee beans before leaving & was pleasantly surprised that it came with a free coffee. i went with an americano & it was excellent! very nutty & enjoyable. would def come back for it!
