Three Sixty Lounge is a lounge bar on the 31st floor of the Millennium Hilton Bangkok, where guests drink cocktails while looking out at the Chao Phraya River at night. It has separate indoor and outdoor areas, so on hot days guests can stay in the cool indoor space. The venue is not crowded and the tables are spaced far apart, making it easy to stay quietly. It is close to ICONSIAM, which connects to an easy route after shopping.
