I loved the Singapore Zoo and Night Safari.
Sentosa Island was fun.
Clarke Quay everyone raves about but I never got that far - so can't really comment.
You need to visit the giant Merlion near the water..I think its close to Clarke Quay.
Little India and Little China are pretty cool areas, and offer some interesting food.
