Are there muslim halal food restaurants and praying room at HKIA?

The praying rooms are available in the airport and they are at Level 6, near Gate 42, Terminal 1 (restricted area) and Level 5, near Gate 501, North Satellite Concourse (restricted area) for 24 hours.
For the muslim food, I am not very clear, so it is suggested to ask the airport staff to know more information.
