九龍灣教會一問

I can recommend two :
1) Kwun Tong Peace Church, I think it is near To Tai Estate (you can check their address on the telephone directory or the internet)
2) Kowloon City Baptist Church - although it is not in Kln Bay, it is easily accessible by public transport

There is actually one on 2nd floor, Li Kee Bldg (Kln Bay MTR) but I forgot its name.
