I haven't been to any Kanda sushi places in ages... I ordered on their delivery service. The service was 45 minutes long which is not too bad. As for the quality of the food, I can say it is not the best out there, more like okay, it is eatable and it fills you up. The price was around 17 to 18$ for 14 sushi (sushi with fishes mostly) and two eggs rolls. I can't complain at the price I am paying because it was cheap for a reason, the fishes are the sort that get refrigerate and defrost for consumption.
Their level of competitiveness has gone down a lot for the past years, others all you can eat sushis are more competitive with nicer decors and better service. It used to be a hot places to frequent for the sushis lovers in Montreal but it has since become a common food and not a luxury food.
I will say it is okay... When you are craving for sushis and your taste buds don't care too much about the freshness of the fishes. Go for it!
