Osmo X Marusan comes across as a stylish, vibrant cafe in downtown Montreal with a lively vibe, strong coffee and a notable lineup of matcha and hojicha lattes, plus creative Japanese inspired sandwiches such as tamago sando and karaage sando and curry bowls; the space and terrace are great for studying or hanging out, and a casual DJ moment adds to the atmosphere, but the place is often crowded and loud with long waits for food at peak times, and some dishes or portions can feel small or uneven while service can be variable, yet the overall experience centers on the ambiance and drinks and many guests say they would return to try new items.
A couple who I met at a bar tipped us off that this is the spot blowing up on IG. Apparently, there's a pretty cool underground cocktail lounge, but we just stuck around for the cafe.
Not sure why, but I almost always defaulted to iced when it comes to matcha & hojicha lattes. I honestly can't remember the last time I ordered one hot, so it was just nice to switch it up & taste something different. Nothing special but still a really solid cup.
The Tamago Sando was fantastic though. Wished the kitchen hadn't forgotten the smoked salmon I added, but even without, it was great. A perfectly fried jammy egg, cracked pepper, & Mornay sauce. Not the traditional Japanese Kewpie mayo route, but this fusion with French Mornay sauce based on béchamel base loaded with Emmental cheese, gave the whole thing a nice savory boost.
Best social café /restaurant/ concept with a smart Japanese touch in MTL. (Thanks to Hideyuki Imaizumi).
Food is simple & great. Prices are really OK.
Feel free to enjoy a cosy lunch there or dive into a musical experience with food & drinks that you will only get there.

National café in a cute Neighbourhood with good decor, nice vibes, delicious coffee, & yummy snacks. I came here after the workout with my partner & we both had different coffees. They were both very good. The staff is nice & the service is quick.
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.
