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.
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.
Quickly served, nice casual laidback ambiance & the food was delicious. Went with the classic tamago sandwich & a matcha latte. Recommend & will go again
The vibe of the place is nice & the food's good. But one of the servers made the experience uncomfortable. Imagine this place came highly recommended by peers & it's your first meal of the day, but the service ends up leaving you frustrated.
The café has a really cozy & inviting atmosphere, but it's not particularly suited for families with young kids. It feels more like a hangout spot for teenagers to socialize or meet new friends.
I tried the matcha latte - it was decent, though I personally prefer a stronger, slightly bitter matcha flavor. For lunch, I ordered the fried egg sandwich & the pork chop curry rice. The sandwich was nicely seasoned & quite enjoyable. The pork chop, while tasty, wasn't the traditional Japanese-style breaded version - it lacked the crispy panko coating you'd expect from a tonkatsu. That said, the curry sauce was very flavorful & well done.
Overall, the food was good, but the portion sizes were a bit small for my appetite.
Super super super service! On Les employés sont vraiment accueillant & à l'écoute. Par contre niveau nourriture j'ai pas trouver ça spéciale voir même un peu fade
Belle trouvaille. Un endroit où plusieurs jeunes branchés viennent travailler ou relaxer avec un livre & un café. L'espace est plus grand qu'il ne paraît, il y a plusieurs tailles de tables différentes. La musique est toujours bonne, & il y a parfois même un DJ présent. Un indicateur de décibels prouve que l'endroit respecte les clients. J'ai particulièrement aimé & DÉVORÉ le sandwich au saumon fumé, concombre & fromage à la crème. DÉLICIEUX. La fraîcheur des ingrédients était magique en cette journée de canicule. J'ai aussi goûté le sandwich aux oeufs, l'oeuf était préparé d'une manière que je n'avais jamais expérienced. C'était trop trop bon. J'ai pris un chaï latte glacé qui était non seulement tout mignon, mais aussi doux & bon, pas trop sucré même s'il était fait à partir de sirop. Mon amie a pris un cold brew, & la foam était majestueuse, c'était comme boire dans un gâteau moelleux. La terrasse est trop belle aussi. Je vais revenir c'est sûr! Surtout que j'ai appris qu'il y a les vendredis cocktails héhé
Great hangout/study space. Egg sando was bland & the bread texture is just okay (not fun to bite into); would recommend getting the Katsu sando in Chinatown instead. Chai Latte is also lacking flavor but not offensive.
