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.
i got the tamago sando which looked better than it tasted. 😆 it was just mayo & salt, which was a bit plain for me. the flat white was also just okay.
the café was super busy even on a tuesday afternoon, probably because it's close to McGill, with lots of students on laptops. It was also pretty noisy, but the space itself was well designed & very aesthetically pleasing.
i grabbed a bag of coffee beans before leaving & was pleasantly surprised that it came with a free coffee. i went with an americano & it was excellent! very nutty & enjoyable. would def come back for it!
Malgré le décor mignon & la nourriture bonne (nous avons essayé des cafés, matchas, tamago sando & karaage sando), nous avons vraiment eu un service vraiment désolant qui nous a donné une expérience négative au total. Lors d'une erreur faite par le staff (matcha chaud au lieu de glacé, matcha sans sirop au lieu de matcha érable), nous nous sommes faites blâmées pour cette erreur & on s'est fait addressées vraiment bêtement, de manière borderline passive-aggressive & impolie même si on a mentionné l'erreur gentiment. Même plus tard, on s'est faites servir avec attitude & & on s'est faites dévisager lorsque l'on a demandé pour une boîte à emporter. C'est réelleement dommage de se faire servir ainsi quand on paye à l'avant & on donne un pourboire même avant d'évaluer la qualité du service. Je travaille en restauration & jamais je traiterais des clients de la sorte, qu'il s'agisse de leur erreur ou de la mienne.

Had the Tomago Sando which was really good & also tried the hojicha latte & yuzu lemonade. The lemonade was sour & not too sweet in the best way. I would recommend all of these items. It is a unique space that is well decorated. When we visited on a Saturday afternoon it was busy & there was a dj playing, so it was pretty loud. It doesn't have the relaxing atmosphere I would usually enjoy at a café.
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.
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.
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.
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
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

Bon café mais leur sando(sandwich japonais) faits d'Osmo un must try in MTL. Ambiance uniqe une superbe terrasse en arrière qui vous donne l'impression d'être sorti de Montréal
I came here for a quick lunch. The place was very busy. You can tell it's a popular place among students. After ordering at the counter, they give you a number to place on the table & they bring your order to you when ready. The café is nice but quite noisy so it's not the ideal place to sit & study. I ordered the famous tamago sando. It was ok, not great. Apart from the egg, the rest of the sandwich was bland. Just too much bread. On the other hand, the chicken sandwich was very tasty.
