For the outbound SFO-OGG you'll have breakfast. Should be three choices, one of which will be cereal and fruit, likely. Nothing special on the hard product; standard 757 seating.
The 777 HNL-SFO is the "Hawaii configuration", so you'll have the quasi-barcalounger seating, so at least a footrest and a better recline than the standard domestic seat. You'll also get the fuller pillow and blanket, yes. This should be a snack based meal...something along the lines of a wrap or a sandwich.
