High above Seoul on floors 76 to 101 of Lotte World Tower, SIGNIEL Seoul looks across the Han River, the city grid and distant mountains. Rooms and suites use a restrained contemporary palette, Korean motifs and broad wall-to-wall windows, with thoughtful service extending through the Salon de SIGNIEL lounge. STAY by Yannick Alléno occupies the upper floors for French dining, while Bicena presents modern Korean cuisine and Bar 81 faces the skyline. SIGNIEL Spa, an indoor pool and fitness facilities form the wellness level. The tower’s tapering glass profile and extraordinary elevation define every public room and corridor.
