I heard about Kazu almost as soon as I moved to Montreal 4 years ago. I finally had the chance to go last night. My hubby and I followed recommendations and ordered the shrimp burger, salmon tuna bowl and the bbq chicken tortilla. TBH, we weren't that impressed. Sure, everything tasted good, but so does anything once you drown it in mayonnaise or other sauces. We left feeling a bit gross (since the food we ate was not healthy). The salmon tuna bowl barely had any salmon or tuna - just mostly rice. The shrimp burger was good, yes, but had way too much mayonnaise. There was definitely nothing subtle about our meal.
However, I think I need to go back. I think if I were to do it again I would get the salmon belly or pork neck.
Also, I want to add that the service was amazing. Our waitresses were so patient and kind! We got in line at 5 pm and were the first to be seated. When we left at 6 pm, there was a line out the door on a Thursday night. Just FYI.
