Singapore's nightlife isn't quite a match for Patpong, but it's no slouch either. Some clubs have 24 hr licenses and few places close before 3AM. Any artist touring Asia are pretty much guaranteed to stop in Singapore, with superclub Zouk in particular regularly clocking high on lists of the world's best nightclubs. Singapore's nightlife is largely concentrated along the three Quays — Boat, Clarke and Robertson — of the Riverside, with the clubs of Sentosa and nearby St James Power Station giving party animals even more reason to dance the night away. Gay bars are mostly found around Chinatown. Drinking age is 18, and while this is surprisingly loosely enforced, some clubs have higher age limits.
Friday is generally the biggest night of the week for going out, with Saturday a close second. Sunday is gay night in many bars and clubs, while Wednesday or Thursday is ladies' night, often meaning not just free entrance but free drinks for women. Most clubs are closed on Monday and Tuesday, while bars generally stay open but tend to be very quiet.
For a night out Singapore style, gather a group of friends and head for the nearest karaoke box — major chains include K-Box (http://www.kbox.com.sg) and Party World. Room rental ranges from $30/hour and up. Beware that the non-chain, glitzy or dodgy looking, neon-covered KTV lounges may charge much higher rates and the short-skirted hostesses may offer more services than just pouring your drinks. In Singapore, the pronunciation of karaoke follows the Japanese "karah-oh-kay" instead of the Western "carry-oh-key".
Alcohol is widely available but very expensive due to Singapore's heavy sin taxes. On the other hand, tax-free at Changi Airport has some of the best prices in the world. You can bring in up to one litre of liquor and two litres of wine and beer if you arrive from countries other than Malaysia. Careful shopping at major supermarkets will also throw up common basic Australian wine labels for under $20.
Alcohol is haram forbidden to Muslims, and most Muslim Singaporeans duly avoid it. While most non-Muslim Singaporeans are not puritanical and enjoy a drink every now and then, do not expect to find the binge-drinking culture that you will find in most Western countries. Unlike in most Western countries, public drunkenness in socially frowned upon in Singapore, and misbehaving yourself under the influence of alcohol will certainly not gain you any respect from Singaporean friends. Do not allow any confrontations to escalate into fights, as the police will be called in, and you will face jail time and possibly caning.
Prices when eating out vary. You can enjoy a large bottle of beer of your choice at a coffee shop or hawker centre for less than $6 and the local colour comes thrown in for free. On the other hand, drinks in any bar, club or fancy restaurant remain extortionate, with a basic drink clocking in at $10-15 while fancy cocktails would usually be in the $15-25 range. On the upside, happy hours and two-for-one promotions are common, and the entry price for clubs usually includes several drink tickets. Almost all restaurants in Singapore allow bringing your own BYO wine and cheaper restaurants without a wine menu usually don't even charge corkage, although in these places you'll need to bring your own bottle opener and glasses. Fancier places charge $20-50, although many offer free corkage days on Monday or Tuesday.
Tourists flock to the Long Bar in the Raffles Hotel to sample the original Singapore Sling, a sickly sweet pink mix of pineapple juice, gin and more, but locals almost never touch the stuff. The tipple of choice in Singapore is the local beer, Tiger, a rather ordinary lager, but there's been a recent microbrewery boom with Archipelago Boat Quay, Brewerkz Riverside Point, Paulaner Brauhaus Millenia Walk and Pump Room Clarke Quay all offering interesting alternatives.
Tobacco is heavily taxed, and you are not allowed to bring more than one opened pack not carton, but a single pack! of cigarettes into the country. This is particularly strictly enforced on the land borders with Malaysia. Many public places including hawker centres have restrictions on smoking, and it is prohibited in public transport as well. There is a total ban on smoking in all air-conditioned places including pubs and discos, and strict limitations on where you can smoke outside as well e.g., bus stops, parks, playgrounds and all except the designated sections of hawker centres are off limits. The designated zone should be marked with a yellow outline, and may have a sign reading "smoking zone".
Prostitution is tolerated in six designated districts, most notably Geylang, which — not coincidentally — also offers some of the cheapest lodging and best food in the city. The industry maintains a low profile no go-go bars here and is not a tourist attraction by any stretch of the word. Legally practising commercial sex workers are required to register with the authorities and attend special clinics for regular sexually transmitted disease screening. However, please be prudent and practice safe sex--although most sex workers will insist on it anyway.
Orchard Towers, on Orchard Road, has been famously summarized as "four floors of whores" and, despite occasional crackdowns by the authorities, continues to live up to its name. Beware that the prostitutes working here are usually not registered, so the risk of theft and STDs is significantly higher, and note a few of the "women" are actually transsexuals.
