Aqua City Gourmet Pass

Aqua City Gourmet Pass: HK$550/HK$280 for children (including Ocean Park Admission and special 3-course dinner at Neptune's Restaurant in Aqua City, dinner time 18:00-20:30)
Yes, after you bought that pass, you have no need to pay the admission. You can have special 3-course dinner at Neptune's Restaurant in Aqua City without extra payment. You can buy the pass at the entrance of the park.

Thanks for the very fast and helpful answer!
But i think, i will not visit the Neptune’s Restaurant.
The reason is, it will open much to late!!
When i walk some hours through the Ocean Park, that
makes me hungry so so i will eat from time to time and when
the open time of the Neptune’s Restaurant come, my belly will be full.
Thanks again for your answer!!
