Sorry to revive an old thread, but I went to the place hongkong7 suggested below just today and their rates are extremely competitive. Went to exchange HKD for Singaporean dollars -- they sold it to me at an exchange rate of 6.11 when the market is currently at 6.10! I took a casual look around at random street vendors and almost all of them were offering an exchange rate of 6.33. I also noted their exchange rate for the US dollar is 7.7694, which is very close to what my bank (Citibank) offers me.
