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.
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

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!
My hojicha latte was great, I just wish the music was slightly quieter for a better studying environment. The loudness (with the added sound of people talking) made it a bit distracting. Will be back to try the food next time!
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.

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!
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 :)
didn't expect the food to be that good. it was full but my katsu sando was ready within less than 10 minutes. seems like a cool place to go & chill listening to some nice music.
Great music & atmosphere here, the food is delicious but the portions are a bit small. I ordered the chicken katsu curry(??) & there were two small pieces of chicken in it.
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.

Montreal gem!! amazing comforting food & a cozy vibe with good music playing always. perfect study spot, to catch up with friends or even just for a quick bite
Absolutely lovely, highly recommend. The music was a little maouder than what you'd expect from cafe background music, but that didn't bother me personally (the music was very cool)
Also shoutout to the one black barista, you have a very nice & smooth voice:)
great food & cool vibes but definitely not a good place to get work done. it's located semi'underground' & has cool steel decor. the sandos are delicious & their matcha lattes are some of the best in the city! It does get quite loud in the cafe & the music is usually pretty loud too. plenty of seating but not enough outlets if you plan on doing work. Would recommend for going for lunch or hanging out!
