I can't compare as I haven't flown KE in biz, but I doubt they would be the same.
I did a shorthaul F on the A380 the other day. I did not see any pre-order options, and the menu onboard was not extensive. Can't remember the choices, I believe there was a choice between one chinese and one korean type of meal. I had a superb bibimbap. All food was very fresh, tasty and well presented. All utensils, including chopsticks, were silver. I believe there was an excellent choice of wine, but the Laurent-Perrier Cuvée Rosé Brut really won me, so I didn't go through the wine list.
