No-one tips in Singapore. Lamentably, the price of drink in Singapore is not as reasonable as that of food. The two local brews are Tiger Beer and Anchor Beer. Both are fairly sharp lagers. Many bars stock Irish beers, albeit at grossly inflated prices.

Entertainment Singapore offers plenty opportunities for socialising. There are many music bars, although bands frequently specialise in cover versions. In one such club, this writer witnessed the strange phenomenon of a Filipino singer attempting to mimic a Limerick accent la Dolores O'Riordan of the Cranberries. There are plenty of nightclubs, although as with most strange cities, the advice of locals may be required in choosing the most appropriate venue. If only for its excellent jazz music, Somerset's Bar in the Westin Plaza hotel, is especially worth watching.
