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.
Been wanting to come here for a while & it did not disappoint. It is the perfect place to grab a quick lunch & study while you're at it. However it is a bit noisy so i would not recommend studying here if you get distracted easily.
The food & drinks were amazing! I like their hojicha latte & the curry rice the most but all their other options are amazing as well.

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
Beautiful place serving quality drinks & food for a good price. Nice staff, really unique vibe. However, it is super crowded all the time so keep that in mind & come
early!
This place could be better managed. I went there twice but both time the sandwiches are sold out. The second time I went around 1pm… it was not very late for a Saturday. But otherwise very cute place & nice drinks

OSMO X MARUSAN offers modern interior & garden terrace for a summer day hangout.
The cold brew & matcha latte are both delicious drink for a summer day.
Young cool hip vibe. This place was a club or a music venue before turning into a cafe? Serving Japanese street dishes, along with specialty drinks. Very popular, & line can be long, but large outdoor seating can accommodate many customers.
Exquisite cafe: the food, the drinks, the vibes. Will be thinking about the egg sando for a while - it's just so perfectly jammy with the right amount of kick with the side of hot sauce. Matcha also deserves a shoutout: you can tell that it's higher quality matcha. Would definitely come try some of their other sandwiches & drinks again! Also worth noting that you can't order the sandwiches until 11AM.
Loved the vibe & atmosphere so much. It felt chill but they also had a dj there. The place is kinda located in a hidden spot with a weird entrance gate however as soon as you walk past the gate, it's so cool. The food & drinks were also good!
I can't believe we have such a cool place like this in Montreal. The food just blows my mind. I had the egg sandwich, which was perfect. The environment-both outside & inside-is fantastic. For summer, it's just so convenient. The menu isn't huge, but the drinks & food are delicious. I'll definitely be back again!
