I think the people raring this place low, are Westmount workers / residents And perhaps former clients of Kaizen who are unfamiliar with this
type of sushi restaurant.
The location is what use to be one of MTL's most popular and higher end Japanese restaurants : Kaizen Sushi House .
Kaizen was one of our favorite restaurants when I was growing up so I understand the disappointment one might feel if they walk into the same space and expect something more traditional or upscale.
Unfortunately if you know anything about the food industry, you know it's impossible to do what Kaizen did at the price / value of Crystal Sushi. So for this reason I think the reviews are unfair.
I've been to most all you can eat Sushi places in MTL, and this is one of my top 2. Its definitely fresh, the service was friendly and efficient, the lunch price is awesome and the location is accessible, clean casual, and fun to be in.
If I were to say one thing to be improved on , it would be a wider variety of sauces and or "flavors" BUT this is how they keep the prices so low and can offer such fresh produce I guess so...once again it's definitly at the top of it's game for it's kind.
