I can say this lounge would be the worst lounge among all three star alliance airport lounges in Hong Kong.
The lounge is located near gate 40, the self-operated train shall be taken in order to reach the far end of the airport.
The environment is not as good as the other lounges that I have been in Hong Kong.
The food selection is not outstanding and the taste is mediocre. The only good thing is that my gate is very close to the lounge.
If you have the choice to choose, and the gate is near the far end of the terminal. I would recommend United Lounge instead of this one.
