Its nightlife gained notoriety during the Vietnam War for its girly-bars but a lot has changed recently thanks to Vietnam's tourist boom. Ho Chi Minh City's nightlife has grown and diversified considerably, and while not rivalling the range of entertainment of other Southeast Asian destinations, it's still guaranteed to do the job.With everything from rooftop bars and lounges to pubs and nightclubs playing all the latest dance hits, travellers looking to let loose on a night out on the town will have plenty of options in this bustling, neon city.Visitors can start their night off at a rooftop bar or beer garden, from where they can watch the sun set over the busy streets before heading out to District 1. Here the bars and fashionable clubs can be found, particularly on the streets around Dong Khoi and Hai Ba Trung. Travellers can expect to encounter many popular spots for expats and other westerners, where party goers can make use of the bar, dance floor and pool tables.When visitors start feeling more confident, they can try their hand at hitting those high notes at one of the many karaoke bars, for a night of fun and singing. Then they can head over to District 3, where they can attend one of the nightly live gigs, including local rock bands. But if travellers are after something special and really different, they should hop on one of the many dinner cruises that operate from District 1 and cruise down the Saigon River in style. This is the perfect way to relax and spend a lazy evening.Travellers should also note that many of Ho Chi Minh City's bars and nightclubs close early by big city standards, around midnight or when the last customer leaves so anyone looking to keep going until the early hours of the morning will be sorely disappointed.
