You will have access to a lounge, where they will do their best for the pax to have a good moment and proper F&B. But of course it will be not as nice as the "true" one. I am guessing they will use the mezzanine of the K business lounge (which used to be the P lounge before the current one opened).
I understand your disappointment. As suggested by others, you should call the P line and see what are your options.
