I thought WLG was great, the food spread was also quite OK, they had sushi there in the afternoons. There is also a great view of the surrounds from both sides.
I'm not so critical of AKL, the food selection isn't as good as SYD, but they do have a couple of terminals with high speed internet, lots of different seating arrangements and a larger area which opens up if it gets too busy and superb shower facilities (with joico shampoos, etc) which are a god send after a LAX-AKL and a connection through to SYD.
I agree with LAX, it is just fine though v.small, it has all the amenities you need, shower, toilets in the lounge, 2 high speed internet PCs, relatively modern inside (certainly not worn), just the food selection is somewhat lacking (but it's just as bad at the NW & AC lounges next door).
