St. Andrew's is better. Campus is new and my friends daughter is very happy in there. The Father is extremely nice as well and love kids.
Another recommendation. 'Hau Yan' Kindergarten. is in Hau Tak Estate. the teachers are very nice and loving.
Remember do not even consider Salvation Army Ming Tak KG. the principal is aggrogant, rude, and I don't think she even like kids.
For the other 2 KGs I have no idea.
