Last time I ate here was about two years ago, & the food was excellent. Unfortunately, every time I've come back since then, they're either out of food or the kitchen is already closed-& it's only around 1 or 2 p.m.
Here's a an idea for the management: buy more food. That way you can sell more food, make more money, & customers who come for lunch won't leave disappointed
I got the pork sando & mango matcha, which has a beautigul colour to it. The sando was good as well. The place has a cold industrial feel to it but the decoration & lots of sunlight made it feel better.

This cafe was right beside where I was staying in Montreal, so I had to try it out. I was so pleasantly surprised - it is such a vibe! It's quite obvious which items are the most popular, including the egg sandwich which we ordered multiple of. It was certainly delicious, & not something you can order just anywhere!
I also enjoyed all the iced drinks, which came for free with the purchase of a bag of coffee beans.
Great Japanese cafe in the city. The matcha is strong, smooth & umami. Many alternative milk options as well. We got the egg sando & katsu curry. I really loved the curry & the portion was a proper meal size, it looks smaller in photos 😅 The egg sando was also good but, more of a quick/light bite since the bottom half of the sandwich is just mayo ahah. Either way, a must visit for good matcha!!
Before 11AM & when the lunch menu isnt available, the cafe is pretty much empty. But, afterwards it fills up quick. I'd recommend heading there slightly early, like 10min before if you want to get a table with friends or want to work there. Otherwise, there is a ton of seating!
Really enjoyed my visit overall! The matcha was rich & flavorful, & you could tell the mango was fresh rather than frozen, which made a big difference. The café has a lovely atmosphere & is a nice place to sit & relax.
It was quite busy during my visit, so it was a little noisy & made it a bit difficult to communicate with the staff. My food arrived about 15 minutes after ordering, which was reasonable considering how busy it was.
The egg sandwich looked amazing, especially with the perfectly jammy egg, & I was really excited to try it. While the presentation was excellent, I found the flavors a little milder than I expected. The bread was quite simple, & the sauce didn't add much flavor. I think a bit more seasoning or a more flavorful sauce would really make this sandwich shine.
Overall, it's a charming café with fresh ingredients, great drinks, & a welcoming atmosphere. I'd definitely come back & look forward to trying more items on the menu!
Un café/restaurant super sympas avec des plats d'influence asiatique qui sont très bon & qui remplisse! Je recommande pour les pauses travails entre 12 & 2!
This place has been on my list for a while & I was finally in the area today, so I thought why not.
It was extremely busy & loud which made it difficult to communicate with staff. I placed my order & it was brought to where I was seated about 15 minutes or so later. It looked absolutely delicious & I love a jammy egg...
... but it barely tasted of anything at all. The bread seems to just be regular American style white bread, & whatever sauce they use is completely flavourless. I don't even know what it was. I can't even compare it to anything because I couldn't identify even a single flavour within. It's trying to be a quirky version of the Japanese style egg sandwich but it's completely unnecessary.
Sitting there, you quickly realize that this is yet another place that exists for vibes, stories, & to blow up online thanks to influencer content - & yeah, I was one of the people influenced, that's why I came here haha. People around me taking tons of photos & selfies & video recordings of themselves trying everything they ordered... which is fine. I took a picture too. But it's clear the food here is made to be Instagrammable over all else.
On the plus side, the coffee was good & the service was warm & friendly. But overall, this place didn't live up to the hype for me personally.
