Located at Jungang-ro, Gunsan, Leesungdang is the oldest bakery still in operation in Korea. Its signature menu items are buns with red bean filling and the vegetable bun, which, despite being baked multiple times a day in set intervals, command enough respect to create separate lines for the buns. If enough people are waiting, the bakery even imposes a limit on the number of buns one can get. Other popular menus include sandwiches and milkshakes, which are made to order.
