The restaurant's name is derived from the Korean word "mul," which means "water," and is intended to be enjoyed like a waterside park. The restaurant's open atmosphere, with the outside and the restaurant connected to each other, allows anyone to enter without hesitation.

Otsuka's cuisine is based on recipes passed down from her grandmother to her mother. She uses as little seasoning as possible and emphasizes the umami from the kelp and iriko (dried sardines) broth.

The signature dish, which has had many fans since the time it was sold at handmade markets before the establishment of the restaurant, is Chang's vegetable kimpa wrapped with eight different kinds of ingredients. The gentle taste, which is made with Japanese broth and favored by the Japanese, can be enjoyed when you are hungry, for lunch, with a glass of wine, or to finish off a drinking party. It is suitable for a variety of situations.
