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.
Osmo is a must-try spot known for its flavorful & perfectly cooked sando & Japanese style curry. While grabbing a table during busy hours can be challenging, it's definitely worth the wait for the delicious food. Coffee & other bevs are great, too!
C'est un endroit sympa, le staff aussi. Mais en pleines saisons étudiantes, c'est plutôt insupportable comme endroit. Tout le monde est sur son ordinateur portable, ils prétendent tous travailler alors qu'en fait ils sont sur Amazon... Ils font semblant de ne pas voir que les gens attendent pour s'asseoir, n'attendent pas leur tour. Donc en effet endroit très sympa, bonne bouffe, juste une atmosphère glauque d'étudiants hyper égocentriques, & tellement névrosés qu'ils n'osent même pas regarder les gens dans les yeux, tellement ça serait admettre leur défaite face aux écrans qui leur prennent toute leur attention.
Great atmosphere. It's in a modernist sort of bunker with bare concrete & nice light. It's set up as a cafe populated mostly with students & with huge speakers & a DJ. Probably a great place for clubbing too. The food is perfectly acceptable but not great: steam table curries. Miso soup was very good.
Drinks - I've only had their matcha latte & it's good! No complaints! However!!! I thought I'd treat myself so I got a katsu curry for lunch. It looked great! Plated nicely but WOW was it bad. I couldn't finish the meal. The curry was tasty, but the katsu itself was the worst I've ever had. They didn't trim the silver skin off of the pork!! & if you've ever cooked pork you know to trim that stuff off before cooking. Silver skin doesn't break down when cooked & becomes tough & chewy because it's made up of elastin (versus collagen, which breaks down when cooked). It completely ruined the texture of the katsu. I forced myself to eat some of it (because I paid my hard earned money for it😭) before the texture of the meat made me feel sick. I let the staff know but unfortunately they weren't able to help & I would have to pay if I wanted something else. So I tried to make it work & took another bite of the katsu. It looked like lean meat so I thought I was in the clear, but the silver skin was hiding lmao! It was so chewy I had to spit that out too. It was as if I was chewing meat flavoured bubblegum. I've never experienced this when I've had katsu anywhere else. Truly such a disappointment. To make it worse, the rice was also mushy. How do you screw up rice if you're serving Japanese food? That was the icing on the cake. What a waste of food. All that is to say that I would not recommend the katsu curry.
The overall experience was good. However the drinks that we ordered, the limonade & the matcha latte were not strong enough for me. The matcha tasted almost like green milk. The curé was supper good, the egg sandwich didn't taste anything special, my expectations were kinda high due to instagram. The sandwich does look really good & aesthetic but it isn't worth the hype. But the overall experience was really nice.
Highly recommend - one of the few places in the area that delivers delicious & fresh food. The staff is kind & the space has this cool & cozy atmosphere with lots of windows. Would go back many times over!
Went there for late lunch (week-end). It was difficult to find free seats for 2 persons (lots of people studying/working with their laptops there). The food came out quite fast & the service was good. I feel like the tamago sando is a bit too hyped, recommended for those who never tried it. The taste was normal to what I expected. The katsu sando & the curry was yummy. The best part was the coffees! Would come back just for the Hojicha latte (with white choco).
