Buy lots of durians for taking back to your hotel, just dont get on a bus or mrt with them =)
My missus has been working there the past 10months, I went over for 10 days in March but cant remember the names of places, there was a good cocktail bar called something like blue moon? china town is good for little trinkets, food everywhere is cheap and good, well the meat isnt as good quality as here. Hocker centres are brilliant for eating out, spoilt for choice!
