Osmo X Marusan comes across as a vibrant downtown Montreal cafe with a Japanese inspired menu that features Tamago Sando, karaage Sando, katsu Sando, curries and a range of drinks like matcha and hojicha. The space is stylish and unique, with a lively vibe that often includes music and a decibel meter, which suits many visitors but makes quiet study difficult. A predominantly student crowd during peak hours means long lines and crowded seating, though there is a back terrace in warm weather. Food portions vary with karaage and katsu getting praise while some egg sandwiches feel plain or small; the matcha is usually highlighted as a standout and the hojicha well liked, with a few notes about pre made or underwhelming matcha. Service is typically friendly though some experiences report slow timing during peak hours or occasional missteps. Overall the cafe offers bold flavors and a memorable atmosphere, exceptional drinks, and creative sandwiches, balanced against seating availability and noise levels.View restaurant profile
