Ganjitsu Black sits next to Haeundae Grand Hotel in Haeundae, Busan. At lunch it serves Japanese home-style meals, and in the evening it becomes an izakaya with drinking snacks and sake. The menu includes suji oden tang, motsu nabe, and katsu, and udon noodles can be added to the motsu nabe. Private rooms have tatami-style floor seating with a cutout under the table, and an actual ID card or passport is required to receive a sake cup.
