So here goes:
Bus starts running at 4:30pm, not 4:00. Just FYI.

Security at TBIT was a pain - very crowded and long lines, but I was still the first person to access the First Lounge. Do they hire models exclusively to man the doors?

The lounge is beautiful, but more impressive are the staff. I was amazed to find the level of professionalism that they all demonstrated, and the food was excellent. I had the squid, sashimi, and Korean burger. Absolutely incredible.

I like the design of the Business lounge MUCH more than that of the First, but it was really, really crowded. I didn't even stay for a drink, just went back to my place in the FL.

Now that I've been through the lounge in SYD I see the tie-in with the decor, but it's unfortunate that there wasn't more done to differentiate the space in LAX. I suppose for the smaller space, it's been done about as much as can be.
