Ganggane Son Mandu Jangsan serves hand-made mandu and kalguksu in Busan. The menu includes meat-juice mandu, tteok mandu guk, and sujebi, and prepared mandu and fried mandu can be bought to take away. Meat-juice mandu should be eaten as soon as it arrives, because the wrapper dries out over time. In the small dining area, staff are seen being repeatedly shouted at by a customer.
