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.
Cool decor & music. The matcha with chocolate is delicious & makes you want to come back for more. The salmon sandwich is another delight. Once I came with my laptop to work but the place is too loud & there is much food smell like eggs & garlic so it's not really a place for that.
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.. 😂

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!
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.

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.
Maybe its because it was Friday afternoon but the music was too loud & the genre kept changing every music so it wasn't a great place to work on your laptop. But the matcha was delicious.

They had the best karaage that I've ever had in North America so far. It is so juicy, tender & well-seasoned, always comes in fresh. They not just put the starch outside, but also keep the chicken skin & fried them well, which is really nice!
I would also recommend their matcha latte & h?jicha latte. They taste great as well!
The only downside for their meals is it comes with a small portion, only 2-3 pieces of chicken is a bit not enough. & the curry itself tastes a bit normal. I also ordered the karaage sandwich version but their bread is a bit dry. But at the end, definitely a big fan of the karaage flavor.
Ordered boiled egg sandwich, & had a matcha latte for the first time here. The sandwich was excellent, not over seasoned or soggy-nice & simple. The matcha was rich but not too heavy. The barista was very concentrated & careful while making it. The space was thoughtfully designed & clean without feeling sterile. Great experience overall.
Osmo is a perfect vibey place to chill & study on a rainy day….. their matcha is the BEST in town & I love that it isn't clumpy & oversweet like other places in the city that serve matcha. Also everyone that works here is a beautiful angel…. I come here a lot & have never gleaned a bad vibe. Just perfection! They will make ur day😁💓💓💓
found this little spot in a TikTok video I was sent. pleasantly surprised! Kinda hard to find at first.
We had a matcha & a coffee, around 15-20$ for both. love the vibes, alot of students, & some good background music (music that was a little too loud?) other than that, no other gripes. just a cool place to visit if you want to see something different in Montreal :)
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!
