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.
Came here to find out what the hype was about.. we came a bit before they serve the sandwich. But there was a prob that occured, the air fryer was broken so we had to wait almost 40 min to get our sandwiches. Bc I wanted to try it so so bad & we were already there, we waited..
The food came, & honestly the taste was ok. It was not wow but it was a normal sandwhich that u could make at home.. also the karaage was tiny that I had a couple of bite with just bread & no chicken lol. Also the tamago is ok not too tasty..
Also ordered their Hojicha Latte & this was really good!! 10/10 , croissant is ok as well..
It's good to try once but not smt I'd drive 40min to try again 🙂🙂 Staff are very nice tho!!! :))
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.

8 really great tamago sandwich with smoked salmon was amazing. Chicken katsu sando would also be great to try. Def come again. Chicken curry was good but hyuga curry is better & sando is a better choice. Tamago with smoked is a great orde
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 used to love this place but they are now giving everyone buzzers that go off when their food is ready. It's continual jump scares as these things go off, clanging against the metal tables. Completely destroys the atmosphere.

Phenomenal place to sit & enjoy your day. Great ambiance & the food is just legit amazing. Got a coffee & a karate sandwich & both of them were just delicious. I wish I could've tried everything else in their menu. Keep up the good work guys
J'ai eu un vrai coup de coeur pour ce coffeeshop un peu caché, à l'ambiance arty. Ce n'est pas juste un endroit pour boire un café, la proposition culinaire est vraiment à la hauteur, j'ai adoré. J'y retournerai sans hésiter !
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!
The tamago sando (egg salad sandwich) looks better than it tastes. The concept of a scotch egg in a sandwich sounds cool but the execution was a bit underwhelming. It does not tasted bad but it's also quite forgettable. The mayo is def not what you typically get in a Japanese style sandwich, tasted quite bland & greasy. I think they still has potential, will prob go again to give the chicken & Katsu sando a try
The vibe was cool but def don't expect it to be quiet
