Sumosan at Six Senses Residences Courchevel will open in Dec 2019 as an exciting addition to the much loved Sumosan Japanese restaurants. Sumosan's first Alpine outpost, at the heart of Courchevel 1850, offers its signature sushi and dishes. The bar will provide the ideal après-ski destination, shaking up cocktails until late. Six Senses Courchevel sits in the largest linked ski area in the world.
