In my case, I give out gift pack when ppl give gift/ang pow..   

As for which catering to use, I did make a call to some catering service but some only offer delivery if I order a lot.
And some catering offer curry chicken only which I have a concern as not all ppl would immediately eat it once received the fullmoon packet.
FYI: Curry chicken cannot last long...

Finally make a call to Delight Fullmoon and was satisfied with their food, service and delivery.
The delivery arrive in the morning, and I immediately send out during lunch hour whcih becomes their lunch   
FYI: The food is not warm, and need to reheat
