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.
Excellent repas & les boissons étaient vraiment bonnes mais difficile de trouver de la place.
Un peu bruyant aussi si vous voulez un endroit pour travailler/etudier.
Le service était impeccable.
Was super excited about the egg sandwich but got disappointed bc the kitchen only starts at 11am while the coffee itself opens at 10am. My flat white vanilla was very good & the hojicha is good for who likes matcha!
The curry bowls here are the perfect size for lunch & are very delicious. The matcha was also tasty. They are not sweetened though in case you are looking for a sweet matcha latte. It was very busy when we stopped in but we were able to find space on one of the shared long tables very quickly.
I have been to this place with my boyfriend, we had the famous egg sandwich, tea & coffee! Everything was delicious, the ambiance is soo fun! I came back last week for the Christmas market & again, the vibes are immaculate 💓
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!
Beautiful place serving quality drinks & food for a good price. Nice staff, really unique vibe. However, it is super crowded all the time so keep that in mind & come
early!
Un très beau café au design unique, avec un menu d'inspiration japonaise qui se démarque. L'endroit est populaire auprès des étudiants, donc ce n'est pas l'adresse idéale si on cherche un moment calme.
Nous avons pris un matcha & un osmo fog, tous deux bien exécutés. Les sando étaient bons, mais manquaient un peu de saveur selon moi.
Malgré tout, l'expérience globale reste plaisante & je retournerai chez Osmo x Marusan sans hésiter.
Really interesting looking place, the vibes are so cool. Definitely targeted to a younger university-aged crowd though. Also very loud at times. There's a dB meter that helps you keep track at least.
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.

It's a nice small cosy café in my Neighbourhood, which I have never seen before I discovered it because it's kind of like a hidden Café. I've tried their much with lavender, which was tasting good. Also, they had nice sandwiches. I haven't tried yet, but they looked very good. Maybe next time I will try that too.
The place is littered with laptops & people out overextend their stays. Choose your time wisely if you plan to visit this hidden gem. Feels more like a library with food than a great café with food.
Limited seating time would be a great suggestion for this place.
