Never flown EK302, but have flown EK366 a few times over the years, which departs a little later at 03:40. It was always a snack after take off, and breakfast before landing. I assume the service to be the same for all the flights bound for far east in the same departure bank.
And I always eat in the lounge and skip the snack to maximize sleep. Quite a few people have done the same during my flights.
