The Omakase Experience
We serve an Omakase experience, which means “to leave it up to the chef”. We invite you to our omakase experience as a performance, our bar as the stage and you as our audience.  As our guest, you are encouraged to trust our chefs to select and serve the finest ingredients  available for the day.

Welcome to our humble establishment at Nordenskiöldsgatan 24.
