The way the service flow goes like this: First carts will have made in Hawaii "cinema snacks", DiGi players and headsets for sale. The second cart will be a complementary beverage service including the "pau hana" snack mix. Next, the cart with the free food as well as upgraded buy on board food will come through and finally a coffee/tea service. Based on that normal flow, food does indeed come about 2 hours into the flight. My suggestion is to eat breakfast in the airport and you'll be ready for lunch when the food comes around. Enjoy your flight.
Thanks for the detail! The flight is scheduled for 6.5 hours, so there's really no rush. I will just make sure to have a bagel or pastry at the airport before the flight.
