1 Altitude Bar boasts the highest views in Singapore, and arguably some of the best. This bar, on the 63rd floor of One Raffles Place, has a 360-degree vista and unlike many of its counterparts, there is only a thin, shoulder-height glass panel to stop people falling off the edge, which offers a real on-top-of-the-world feeling. Serving a decent variety of cocktails and hosting a live band and DJ, it is one of the most popular places to watch the sun set and party the night away.
