In Seoul, restaurant closing times vary, but many places typically stay open until 10:00 or 11:00 PM. However, in popular areas like Hongdae, Itaewon, and Gangnam, numerous eateries, including restaurants with private rooms, stay open much later, sometimes until midnight or even 2:00 AM. For those seeking a late-night bite, Seoul’s vibrant dining scene offers plenty of options well into the night.
