Osmo X Marusan comes across as a vibrant downtown Montreal cafe with a Japanese inspired menu that features Tamago Sando, karaage Sando, katsu Sando, curries and a range of drinks like matcha and hojicha. The space is stylish and unique, with a lively vibe that often includes music and a decibel meter, which suits many visitors but makes quiet study difficult. A predominantly student crowd during peak hours means long lines and crowded seating, though there is a back terrace in warm weather. Food portions vary with karaage and katsu getting praise while some egg sandwiches feel plain or small; the matcha is usually highlighted as a standout and the hojicha well liked, with a few notes about pre made or underwhelming matcha. Service is typically friendly though some experiences report slow timing during peak hours or occasional missteps. Overall the cafe offers bold flavors and a memorable atmosphere, exceptional drinks, and creative sandwiches, balanced against seating availability and noise levels.
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.
I loved the architecture of this place, it's so chic…. I had the matcha cookie with my yuzu lemonade & the cookie was so fire… the lemonade is also objectively very good, I am someone who enjoys a painfully sweet lemonade so it was a tad sour but also still very enjoyable. The music they play in there is also groovy. They sell some records too for good prices so I'd definitely recommend to check out with friends!
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
Lovedddd the coffee & this delicious vegan curry bowl! For a place with only one vegan option, it's truly delish - & I'm always happy when the coffee slaps!

Excellent repas & les boissons étaient vraiment bonnes mais difficile de trouver de la place.
Un peu bruyant aussi si vous voulez un endroit pour travailler/etudier.
Le service était impeccable.
Was super excited about the egg sandwich but got disappointed bc the kitchen only starts at 11am while the coffee itself opens at 10am. My flat white vanilla was very good & the hojicha is good for who likes matcha!

The curry bowls here are the perfect size for lunch & are very delicious. The matcha was also tasty. They are not sweetened though in case you are looking for a sweet matcha latte. It was very busy when we stopped in but we were able to find space on one of the shared long tables very quickly.
I have been to this place with my boyfriend, we had the famous egg sandwich, tea & coffee! Everything was delicious, the ambiance is soo fun! I came back last week for the Christmas market & again, the vibes are immaculate 💓
