My favorite bite of food along my trip in Montreal came from Park. There is something so beautifully simple yet insurmountably complex about fantastic sushi and Park nails it on ever level.
A friend of mine had been a regular here during a 3 month work trip and gave me the advice that I will pass to you now - get the Maki and the Nigiri, everything else is just good. The Maki and Nigiri were amazing and as for my favorite aforementioned bite, that goes to the mackerel nigiri special, pictures top right below.
Service was great as expected but the food and the value (as we were shocked at how low our bill was for what we ordered) stand out.
