My elder son used to visit Dr. Leung Yin Kwan, Bernard, 1/F of the plaza and opposite to 'Tai Ka Lok', but my younger son doesn't fit him. (Fee: $160 - 180). So it depends on if the patient match with the doctor. I have a friend's husband is a doctor, but her son still need to visit other doctors!
Another doctor(female) I myself used to visit is 徐頌慈, but if you visit her after 6 p.m., you better have advance appointment first. I like her medicines are not so 散. In the past, I visited another female doctor whose clinic was on the ground floor, somewhere near 'Dynasty' hairsalon, the dosage was so high and made me very unwell, though it was effective to cure my cold finally. The feeling was not good.
