The Singaporean dollar (SGD) is used here.
I haven't bought a bottle of water, but I imagine a 1.5 liter bottle is no more than about $2 SGD.
My favorite meal of all time is the pineapple fried rice served at the Thai stall of Yusef Ishak house, which is a central eating place for the greater university. It costs only $3 SGD. and it's the best meal I've had here. I went there almost every week!
I listened to a lot of old Hispanic music this week since I was showing my friends what I like, including Selena, Celia Cruz and Los Lobos.
The most fun thing I did this week was spending time with my suitemates watching the 1997 Whitney Houston version of "Cinderella" starring Brandy.
The last thing I read was Umberto Eco's Name of the Rose for a class assignment. It was pretty good!
