I found the service to be very personable (particularly when you sit at the bar). My friend is gluten free and usually brings his own tamari sauce, so when he took out his bottle, the sushi chef looked at it and was "ah no no put that away, we have". The chef disappeared into the kitchen and brought back a huge bottle of San-J gluten-free tamari sauce for us to use. Love that they have that available for guests.
As for the food.. It was okay or "eh, not bad" as my friend said. We mostly stuck to nigiri. Presentation and the cuts of fish could have been a bit better. We were able to get customized items to accommodate my gluten-free friend, including a sake shooter using the gluten-free tamari sauce.
