For a nice evening out, Nancy and I went to n Grill, a revolving restaurant at the top of N Seoul Tower which provides the city's highest viewpoint. The tower serves as the antenna for various local and nationwide FM and TV broadcasting stations and opened in 1980 as a hybrid recreational/cultural complex.
Nancy and I enjoyed our dinner at n Grill but the movement made us both a little queezy. The view was spectacular and until then I didn't know how beautiful Seoul is at night.
We also got a nice view of the city's evening skyline from the ferry. Nancy insisted we take a ride along the Han River which runs through the center of Seoul. In some respects it is like the Seine but much wider. Within city limits, its width measures 1 km.
