Ddattung is a Chinese restaurant inside the Riverside Hotel in Seoul that serves Beijing duck, course meals, and à la carte dishes. The Beijing duck keeps both the crispness of the skin and the savory richness of the duck fat, and ordering several à la carte dishes rather than a course suits the place. All the rooms are separated into private spaces, which fits family gatherings and small group meals, and rooms with windows are hard to reserve. Rooms without windows, closed in on all sides, are on the dark and cramped side.
