hi!
I have been to Dr.Christopher Yu
hes is chineese but speaks really good english - studied in the uk i think
he is somewhere in the central building - dont quite remember what floor.
Check out www.polyvision.com.hk They have 3 centers in Hong Kong (Wanchai, Mong Kok, Shatin). I went there with eye/vision problems and received excellent care for a very reasonable price. I went to their office in Mong Kok, everybody there spoke very good english.
