Disclaimer: I visited this lounge quite a while ago, so things may have changed since my visit.
When I visited this lounge, I was connecting from an international first class flight to a domestic first class flight. According to oneworld lounge rules, I should have had access to the Qantas First Class lounge in the international terminal of LAX since I was an international first class passenger on a oneworld flight. That being said, when I tried to get into the lounge, one of the lounge agents was adamant that I shouldn’t have access. When I tried to bring up the oneworld website to show the agent the actual oneworld lounge access rules, another of the agents mentioned that he had never actually read the lounge access rules before… So I’d say that unless it’s the “typical” case of departing LAX on an international oneworld flight in first class/having oneworld emerald status, you might be in for a fight about getting access. (The agent did make a “one-time exception” for me given that the lounge was pretty empty at the time).
The lounge is essentially one enormous room with tons of seating. There’s tons of seating both in the dining room and otherwise. The lounge chairs by the window seem especially popular.
There’s no self-service buffet, but there’s an extensive made-to-order menu. The food reminded me a lot of the Qantas first class lounges in Sydney and Melbourne, both in that everything is done by table service and the actual food items.
I didn’t have much to eat since I was still full from my previous flight, but I ordered a couple of items to take one for the team. I ordered some eggs over medium, and the eggs were cooked correctly although they were over salted. The bread served with the eggs was good, and more airlines should have better bread. The muesli was also pretty tasty, although I don’t know if I’ve encountered a muesli that I didn’t like.
I’d love to come back to this lounge and check out the all-day dining menu. The lounge itself isn’t anything special except for the dining room, but the dining room is very, very good for an airport lounge (it’s worlds better than the newish AA flagship dining room in Dallas, for example).
