The Omakase Experience

We serve an omakase experience of Japanese cuisine.  Omakase here means “leaving your dinner up to our chefs”. We invite you to our experience as a performance, our sushi counter as the stage and you as our audience. You are encouraged to trust us to select & serve the finest Scandinavian ingredients available for the day.
