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.
We had heard about @osmo_x_marusan for years-whispered recommendations, glowing hype, forced influncer stories. A reputation that promises revelation. So when we finally went, our first thought was genuinely:'Did we even go to the right place?'
It quickly became clear that this is a café people come to experience, not necessarily to eat. The hipster-industrial aesthetic is immaculate, concrete, like you're going to a café in that club scene from'The Matrix.' It feels engineered more for Instagram stories & long study sessions than for anyone in pursuit of a truly satisfying meal. The space seems tailored to university students with laptops & deadlines, not diners with expectations.
The food, unfortunately, didn't rise to the myth. The tamago sando came with a strange, béchamel-adjacent sauce that felt both unnecessary & confusing. The karaage leaned heavily into grease without the payoff of crispness or depth, & the bread-for both sandwiches-was simply wrong, missing that soft, pillowy integrity you hope for. The yuzu lemonade? Perfectly fine-but unmistakably just lemonade, not even sure why they use the word'Yuzu.' Not even a faint taste of it.
Ironically, the most enjoyable part of the visit was the Osmo fog-visually delightful, theatrically effective, & perhaps the clearest expression of what this place does best.
We left full, yes, but not satisfied. At all.
@osmo_x_marusan is a café where the vibe works overtime, while the food quietly clocks out early. A place worth seeing once-but hard to crave again, once the fog clears.

Came here with my boyfriend on a Thursday afternoon & it was super packed with people studying but they were able to clear a seat for us to eat. 10/10 service for that!
We got the Karaage Sando & Tamago Sando. We found the tamago sando a bit plain, wish it had a bit more salt or maybe chili crisp 🤔🤔🤔. However, the karaage was delicious. We also shared a Hojicha Latte which was suuuper yummy, definitely recommend that.
We tried the Tamago Sando with the smoked salmon added & the Katsu Sando - both were good! The tamago was super flavourful & the salmon added the perfect touch. The katsu was a standout for us; the pork was incredibly tender & juicy. It's a very busy spot, but the food is definitely worth it.
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.
Really packed coffee place. But their coffee is really good. I took the tamago sandwich which was supposedly their best seller. It was ok. The portion was good, I felt full after, but the flavour was a bit missing. Maybe I just got high expectations from it. Still really good tho! I think their curry are more worth it.
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!
Absolutely loved my experience at OSMO X MARUSAN!! A friend & I visited MTL for a few days & had breakfast twice at this cafe. We got the matcha latte (hot & cold) & both were great. We tried two breakfast sandos: the tamago (8/10) & the katsu (9/10). There was a bit of a line up & waited after ordering but the atmosphere was great & staff were very kind so the wait was not bad. I would definitely make another visit during my next trip to MTL!
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.
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.
Quickly served, nice casual laidback ambiance & the food was delicious. Went with the classic tamago sandwich & a matcha latte. Recommend & will go again
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!!! :))

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
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.
I love to come here to make studying more enjoyable. Ordered almond milk flat white with the matcha cookie (huge & so so good) & for lunch an almond milk chai which was so tasty with the tamago sando. Staff is very nice & fast!
