While the bar is not used, you will notice the carts and galley equipments behind the bar. I actually noticed many activities in that area during my flight from KIX to HKG.
I have a feeling that it might be too costly to rip off the bar and the equipment. I recalled that Hainan Airlines actually took over those premium A330-200s and tried a few "premium routes" between major cities in China, but they obviously didn't work out. They returned those planes to HX, and maybe it is easier and more time saving to keep the forward section untouched and just re-modify the rest of the aircraft.
Honestly it is easy to put those Sky Bars back to use - the chiller is still there but given the low quality of wines served by HX, it is not a big deal. However, they can easily set up a snack bar, which will be necessary on those long flights. It is a nice area to stretch your leg too.
