Took a friend of mine to dinner there last weekend for his b-day (we're both travel/airline nuts). I had been there before but he hadn't and the food was good (and I think he enjoyed the place). Yea, a little pricey but I enjoy the atmosphere and the food IS tasty and interesting. Our waitress was very attentive as well.
We got there at 7 and the place was pretty quiet, but by the time we left around 8:30 it had really picked up (then again a few 747's had arrived while we were sitting eating/watching so that might be why it got more crowded).
Anyway if ya have some time to kill at LAX (or live in the area and want a unique dining experience) check out Encounter.
