The staff is fairly pleasant and the location is tidy, clean, and quiet. The quiet may not be by design though. The food is below average for Montreal sushi. Given that Montreal sushi is usually bad quality sushi to begin with - that's pretty awful. The only reason I'd come back is to furnish my daughter's occasional avocado roll cravings. Even then, ordering in might be the better option.
Side comment: my partner didn't rate the sushi is bad as I did. She said it was average for Montreal.
