I did this run a week or so ago.

I ate, slept for a couple of hours, watch IFE etc and then ate again before landing.
I didn't suffer much from jetlag as I didn't let myself sleep too much on the plane.

The meals are Lunch and Refreshment.

Not sure where the crew were based.

I have posted the menu in the F menu thread in this forum and if interested a full trip report which is here
