Kamkam is a small izakaya in Jeonpo, Busan, serving Japanese-style snacks and mackerel pressed sushi. The mackerel pressed sushi, the signature dish, comes without a fishy smell, and the matcha ice cream is served with caramelized walnuts. Reservations are accepted until 5:30 PM, after which a wait is taken, and nabeyaki has arrived an hour later in some cases. The space is small, so there are not many seats.
