Masamuneya is a local izakaya in Osaka that serves sashimi and dishes such as doteyaki. It offers castella made with fish roe and a sashimi moriawase, and orders are placed using images rather than a Korean-language menu. Alcohol is available during the daytime, and the main branch and second branch are close to each other. Indoor smoking is permitted, so people sensitive to cigarette smoke may prefer to avoid it.
