I visited the HKG Centurion Lounge on Oct 9, it is a step up above the plaza premium lounge decoration and food-wise, there was no crowding at all, about half full at the Platinum area, a sharp contrast to the huge crowd in plaza premium lounge that I visited before.
I visited during breakfast time, the food is delicious. The siu mai and congee are very good. Overall the food is better than the SFO Centurion Lounge.
