Fountain of Wealth. It's considered as the largest fountain in the world. They said that when the fountain stops showering water, walk around the mini fountain in the middle for three times and then wish and it shall come true.
We didn't try it though because we were in a hurry as our flight back to the Philippines is just in a matter of hours. Anyway, I'd go visit this place again when I have plenty of time; probably at least two weeks.
