Don't be confused -- there are two Maiko Sushi restaurants on the Island of Montreal. This one is in the West Island, and the other is in Outremont.
This Maiko is the one I frequent regularly, so I'll review this one.
If you're a sushi connoisseur and are looking for a large variety of the freshest sushi in Montreal, this restaurant is superb! They have an extensive menu of all the classic sushi and sashimi options, as well as some more original and unique concepts. They also have a non-sushi Japanese menu, for those who don't like the idea of raw fish. Their chicken and steak teriyakis are quite delicious.
The ambience is very nice, and the staff is very friendly and accommodating.
A little bit on the pricier side -- I sometimes end up spending $80 - $100 just on myself (which includes a couple of vodkas on the rocks); but I am guilty of over-ordering because I love to have a large selection. Better to go in a group of 3 or 4 and order rolls to share, or just try to limit yourself to 15-20 pieces, not 30-40 like me!
