The KE lounge is quite nice. Ample food and drink and reasonably quiet. Goldarak is correct in that it does get very crowded when an A380 load of passengers desends upon it. WAY better than the lounge at T2, which is still used for the evening 777 flight. I might suggest you spend a little time strolling around the new terminal. Not world class, but a major improvement from the piece of garbage it has been for the last 10-15 years. Enjoy your flight.
