Dongjanggung Chingudeul is a dessert restaurant in Seoul serving patbingsu and patjuk. It uses red beans boiled and peeled in-house each day and 100% milk ice, prepared in an old-fashioned style. An elderly couple runs the restaurant, and bingsu is available for takeout even in winter. The bingsu and patjuk have little sweetness and seasoning, making them unfamiliar to those looking for sweet bingsu or seasoned patjuk.
