Probably the best Chinese bakery in the metro is Ho-land in Binondo, Manila's Chinatown. Their specialty is hopia, flaky puff pastry filled with a sweet mung bean paste—delicious, especially when freshly-baked. They also have mooncakes, tikoy (a glutinous rice cake), peanut cakes, and other Chinese delicacies. They've also expanded the hopia line by introducing new fillings. I think their original hopia is still the best, however.
