I'll be flying CX in first class for the first time in a couple of months, with several hours' stay in HKG between connections.

The facilities they make available to first class passengers sound amazing as they're described on the Cathay website. How much do they charge at the bars, restaurants or for the services at the day spa, or are these actually free? Maybe I'm too used to the 'service' available in the U.S. but it doesn't seem possible that there would be no cost.
