About

Review Summary

Osmo X Marusan is widely recognized for its unique industrial bunker-style aesthetic, beautiful natural lighting, and vibrant, music-heavy atmosphere that attracts a steady stream of students and socializers. The café is frequently praised for its high-quality matcha, hojicha lattes, and Japanese-inspired menu, with many patrons highlighting the egg and katsu sandwiches as satisfying highlights. While the interior design and overall vibe are consistently described as a major draw, experiences vary regarding food consistency, wait times, and noise levels. Some visitors find the portions small or the flavors mild, while others appreciate the fresh ingredients and cozy terrace. Despite occasional reports of slow service or crowded conditions, many guests consider it a must-visit destination in Montreal for its stylish environment and distinctive drink offerings.

Loved this cafe, I ordered the mango matcha, I was told it wasn't sweet but it was. I didn't mind it, but it wasn't the best. They had a good selection of pastries too, & a lunch menu.

Really cool atmosphere, had good music playing in the background (note that it is loud, but it's chill music).

I would recommend!

This is a very trendy place. I saw an influencer go here so I decided to go. It was on a Saturday & there was a bit of a line. I decided to go with the tamago sando & this matcha ice cream treat. Cashier was very nice & helped me with choosing what to order. I got a bit frustrated because at first I received the wrong dessert, & then the server seemed confused when I said I also ordered a tamago sando. Eventually they brought me the correct dessert but I was starting to worry that maybe I wasn't getting the tamago sando, especially since I didn't ask for my receipt. So I eventually got up & went to the cashier to see if he remembered me. I told him how they got my dessert wrong & mentioned my sando. The girl by him started to get defensive about how she remade my dessert. Look, I'm just trying to make sure everything is on track. Anyway, the cashier assured me that things were just very busy. Eventually I got my sando. The dessert & the sando were both very delicious & flavorful, & worth the wait. I think it would've been a better experience if I went on a less busy day.
I will note that there's construction in the area so it was difficult to find the café without asking a local where it was. They have a wooden tunnel that goes from the sidewalk to the café.

It seems as though there has been quite a change with Cafe OSMO. It used to be a very good food but they have completely change their recipes. If you're coming for the egg sandwich don't bother, the egg portion reduced & it's no longer egg & béchamel, it's now just an egg salad sandwich. Wait time was crazy long too even though it wasn't full. Servers are always nice enough

what a treat. this cafe is so cute & has great vibes. the tamagotchi sando was a 4.7/5, wish it was seasoned slightly more but the milk bread & runny yolk were exceptional. Chicken curry was also quite delicious! Marinated perfectly & accompanied with some pickled cucumber & cabbage - YUM! 4.6/5! Lastly the osmo fog & matcha brownie were perfect to finish off the meal. Would come back again, music is elite, ambiance is great & the experience was well worth the wait!

L'ambiance est particulièrement agréable.
Les sandwichs sont généreusement garnis & savoureux & le rapport qualité-prix est excellent. L'établissement est très prisé, ce qui implique une fréquentation souvent élevée.

Very cool place to try out. We got their pork katsu & egg katsu sandos. The pork was alright, but the egg was super tasty! Also had their iced chai, which ended up being a bit watery. Took awhile to get the food, but it's a busy place so bring your patience!
