Looking for Japanese restaurant with Japanese sushi chef serving freshly grated wasabi
I remember having real wasabi at Shiro in Vancouver. I think there was another restaurant too - I think it may have been Octopus Garden.
I think the sushi itself matters more than the wasabi. That being said I would recommend Sushi Hachi in Richmond (need to reserve at least 1 day in advance) or Ajisai (the grilled hamachi pressed sushi is amazing)
