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.
A couple who I met at a bar tipped us off that this is the spot blowing up on IG. Apparently, there's a pretty cool underground cocktail lounge, but we just stuck around for the cafe.
Not sure why, but I almost always defaulted to iced when it comes to matcha & hojicha lattes. I honestly can't remember the last time I ordered one hot, so it was just nice to switch it up & taste something different. Nothing special but still a really solid cup.
The Tamago Sando was fantastic though. Wished the kitchen hadn't forgotten the smoked salmon I added, but even without, it was great. A perfectly fried jammy egg, cracked pepper, & Mornay sauce. Not the traditional Japanese Kewpie mayo route, but this fusion with French Mornay sauce based on béchamel base loaded with Emmental cheese, gave the whole thing a nice savory boost.
Matcha was amazing. Egg sandwich really nice & so was the chicken curry.
Place was very busy & loud music so not somewhere I'd go to relax but would go often for lunch if I lived in Montreal.
L'endroit est cozy, mais le service laisse vraiment à désirer. J'ai commandé un matcha en précisant que je voulais seulement un cube de glaçon & on m'a servi un verre rempli de glaçons. Quand je l'ai mentionné, le barista m'a répondu qu'il avait compris une scoop de glaçons qu'il pouvait en enlever, mais qu'il ne referait pas la boisson parce qu'ils doivent respecter des portions de lait, etc.
On a aussi commandé le poulet curry : la sauce était bonne, mais le poulet était quand même très gras.
Osmo is definitely a different spot in Montreal & worth trying at least once. I had never seen a coffee shop with Japanese food like this, so the concept alone made it a fun experience.
I really loved the salmon cucumber sandwich, & the miso soup was also very good. Next time I want to try their famous tamago sando. The ambiance is unique & the place feels lively, but it was quite loud & very busy around midday.
The only thing that disappointed me a bit was the drink. I ordered an iced caramel matcha coconut latte with extra sweetener, but I honestly didn't taste much flavor & it didn't taste sweet either. The matcha was just okay for me.
Also good to know: the entrance is a bit hidden, & you can enter from Clark Street.
Overall, it was a nice & different experience, especially for the food & ambient.
This place is literally perfect - amazing drinks, delicious bites, incredible atmosphere. Went here twice during a very short stay in Montreal cause it was that good. My favs were the karaage sando with the curry sauce. You don't need it cause the sandwich on its own is delicious & filling but I liked it with the sauce too. Matcha quality is really good & I loved the house made white rabbit syrup with it - wasn't too sweet but added a great milky ricey flavour to it.
Cool decor & music. The matcha with chocolate is delicious & makes you want to come back for more. The salmon sandwich is another delight. Once I came with my laptop to work but the place is too loud & there is much food smell like eggs & garlic so it's not really a place for that.

Un des mes cafés préfère à mtl. Really love the egg sandwich with or without salmon. I really recommend their chaï not a fan of matcha but looks like I should be.. 😂
I loved the architecture of this place, it's so chic…. I had the matcha cookie with my yuzu lemonade & the cookie was so fire… the lemonade is also objectively very good, I am someone who enjoys a painfully sweet lemonade so it was a tad sour but also still very enjoyable. The music they play in there is also groovy. They sell some records too for good prices so I'd definitely recommend to check out with friends!
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.
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.
