About

Well-stewed salmon flesh and a broth of unforgettable deep flavor, precious sea urchin fried crisp with sunlight. Tempura made of fish cakes.

​A single piece of fresh wasabi placed lightly, a strawberry parfait eaten during leisure time. Rammen so delicious it's worth losing for. A yogurt smoothie.
