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.
I love the Macha latte & enjoyed the sandwich over all. But wouldn't recommend if you want to sit down & relax for a while & chill because the environment is a bit noisy & crowded with the students. I rarely got my space on that day. Food are great though

Absolutely lovely, highly recommend. The music was a little maouder than what you'd expect from cafe background music, but that didn't bother me personally (the music was very cool)
Also shoutout to the one black barista, you have a very nice & smooth voice:)

Tried the karaage sando, tomago sando, & matcha latte. Latte & karaage sando were fantastic but I wouldn't recommend the tomago sando. Just a lot of sauce & bread with one boiled egg lol.
I saw the sandwiches on instagram & I wanted to try them, but they were sold out. I had the fried chicken curry, & actually was amazing. The chairs & the tables are metallic, a bit uncomfortable.
Petit bijou caché dans ce coin qui est un endroit excellent pour y travailler sur son laptop ou profiter d'une discussion accompagnée de musique jouant sur ces énormes colonnes qui jouent très bien. C'est seulement dommage qu'ils ferment si tôt.
great food & cool vibes but definitely not a good place to get work done. it's located semi'underground' & has cool steel decor. the sandos are delicious & their matcha lattes are some of the best in the city! It does get quite loud in the cafe & the music is usually pretty loud too. plenty of seating but not enough outlets if you plan on doing work. Would recommend for going for lunch or hanging out!
Good food / coffee. Excessive noise for a "café". They have huge amp speakers & they blast aggressive music up to a limit of 80 dB. For reference the legal limit for workplace noise is 85 dB. Above that, protective gear must be used. When asked to slightly reduce the sound, they refuse & point to their dB meter, arguing that it's under the 80 threshold. I left with a headache.
