Wow, never heard of this at LAX.
Sounds like similar to Frankfurt's FCT, but more private. But I am not seeing the value prop on this. Guess I am not part of the target market.
For me if I have that kind of $$$ to spend on a one time usage of a departure/arrival lounge, I will not fly commercial. Join Netjets or similar. Or just be happy with flying commercial and use the first class lounge.
