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.
loved the sandos, the drinks were also really nice. Would love to come again in the future, very cute spot. A bit hard to find seats though & very crowded

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.
somehow this is the worst japanese food ive ever had. the tamago sando was alright, but not as tasty as it looked. the miso soup was flavorless, which i cannot fathom how you could mess up miso soup, packet soup literally tastes better than this. the best part of my meal was the rice, pickled raddish & yuzu green tea.
Osmo is definitely a different spot in Montreal & worth trying at least once. I had never seen a coffee shop with Japanese food like this, so the concept alone made it a fun experience.
I really loved the salmon cucumber sandwich, & the miso soup was also very good. Next time I want to try their famous tamago sando. The ambiance is unique & the place feels lively, but it was quite loud & very busy around midday.
The only thing that disappointed me a bit was the drink. I ordered an iced caramel matcha coconut latte with extra sweetener, but I honestly didn't taste much flavor & it didn't taste sweet either. The matcha was just okay for me.
Also good to know: the entrance is a bit hidden, & you can enter from Clark Street.
Overall, it was a nice & different experience, especially for the food & ambient.
This place is literally perfect - amazing drinks, delicious bites, incredible atmosphere. Went here twice during a very short stay in Montreal cause it was that good. My favs were the karaage sando with the curry sauce. You don't need it cause the sandwich on its own is delicious & filling but I liked it with the sauce too. Matcha quality is really good & I loved the house made white rabbit syrup with it - wasn't too sweet but added a great milky ricey flavour to it.
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 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.
Came here with my boyfriend on a Thursday afternoon & it was super packed with people studying but they were able to clear a seat for us to eat. 10/10 service for that!
We got the Karaage Sando & Tamago Sando. We found the tamago sando a bit plain, wish it had a bit more salt or maybe chili crisp 🤔🤔🤔. However, the karaage was delicious. We also shared a Hojicha Latte which was suuuper yummy, definitely recommend that.

We tried the Tamago Sando with the smoked salmon added & the Katsu Sando - both were good! The tamago was super flavourful & the salmon added the perfect touch. The katsu was a standout for us; the pork was incredibly tender & juicy. It's a very busy spot, but the food is definitely worth it.
Cute little hidden next an old building & its underground. They have good music sometimes a bit loud but someone went to adjust the sound. Food was delicious. I really recommend the Tamago Sando egg sandwich. The sauce inside with the eggs were a great combination. Keep napkins near, it's a bit messy.
Came here for the first time & ordered the Katsu Sando, Tamago Sando. I had to come a second day as they sold out on the weekend around 2pm. Sandos were tasty, juicy & very good for value. A lot of people look like they're studying/doing work but I feel the music that plays in the background is a little too loud for that kind of environment. I do appreciate the decibel meter tho!
