Osmo X Marusan comes across as a stylish, vibrant cafe in downtown Montreal with a lively vibe, strong coffee and a notable lineup of matcha and hojicha lattes, plus creative Japanese inspired sandwiches such as tamago sando and karaage sando and curry bowls; the space and terrace are great for studying or hanging out, and a casual DJ moment adds to the atmosphere, but the place is often crowded and loud with long waits for food at peak times, and some dishes or portions can feel small or uneven while service can be variable, yet the overall experience centers on the ambiance and drinks and many guests say they would return to try new items.
Immaculate vibes
The matcha is, indeed, a must in mtl
The space is so nice & inviting, but people KNOW SO IT'S PACKED
if you manage to find space pls go!
++++ cause the staff is so nice
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.

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
Awesome little joint, don't be fooled by the exterior. Great sandwiches & to my surprise the Katsu Curry was great too.
As it moonlights as a club it's atmosphere is loud even during day service. There is a decibel monitor in the cafe & it was at 82 when we were there. We didn't wait for a line at 11:30am but the line quickly grew as we waited for our food so be ready to wait as it's a popular spot.
We heard about this place researching for our trip to Montreal & it was great for us.
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.

The yuzu tea was made with Sencha, which is a type of green tea. I didn't expect it to be green tea, & I wish it had been written clearly on the menu. If I had known, I wouldn't have ordered it.
The karaage sandwich had Japanese-style fried chicken, tomatoes, lettuce, & jalapenos. I expected it to be hot, but both the bread & the chicken were cold, which was disappointing.
It also took about 30 minutes to get the sandwich after ordering. You should go there only if you have patience & plenty of time.
We got to osmo right before the rush. My hojicha latte was delicious. Would love to go back to try their sandwiches. Great vibe in there & lovely garden patio.
Le café est extrêmement bruyant, nous avons attendu 15 minutes pour des boissons. Nous avons pris deux matcha cérémonie, & plutôt décevant, pour un matcha de cérémonie, on ne sent pas la qualité du produit, & en plus de cela, il y a du sucre à la préparation, ce qui gâche un peu le goût du matcha.. c'est dommage
Le OXM se cache sous terre dans un véritable espace hors du commun en plein coeur de Montréal. Il se définit comme étant un club social mêlant culture, café & nourriture japonaise. Si vous vous retrouvez dans cette description alors vous allez adorer le lieu & son ambiance. Mention spéciale pour le tamago sando & le osmo fog.
My family came in August 2024 as we were craving Japanese egg sandos. To our surprise, the katsu sando was even better than the egg sando. The fillings were plentiful & flavourful, & we recommended this place to friends as well.
We passed by Montréal again on a road trip & stopped for a quick bite. Our second visit was still good, but the katsus were much thinner than the year prior (as evidenced in the attached photos). That said, I'd still recommend this place for anyone who wants to try authentic Japanese egg or katsu sandos.
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.
