15/e organic Comment (from a Registered Dietitian)

In this collaboration menu, we have created a nutritionally balanced dish by combining the high-quality protein, essential fatty acids such as DHA and EPA from seafood, with abundant vitamins and dietary fiber found in naturally grown vegetables.

Seasonal ingredients are at their peak in deliciousness and nutritional value throughout the year. By combining these, we have prepared a seafood rice bowl that allows you to enjoy the "inherent flavor of the ingredients" unique to this season, while supplementing nutrients that tend to be lacking in daily meals. Please enjoy this special 7-day limited culinary experience that can only be tasted here.
