In the 1970s, a small food stall located in Keelung's Saochoutou, operated by a pushcart every midnight, offered simple settings and affordable Japanese cuisine, which was highly praised by many gourmets. By chance, the second store, "Yi Er," was established in 2002. The restaurant adheres to the business philosophy of providing good food at a reasonable price, using simple ingredients to tantalize your taste buds, and offering customers the most satisfying dining experience.
