Pretty decent lounge which is better than most Airline lounges in North America. And a bonus is that all you need is an AMEX charge card to enter (Platinum gets in free, Gold gets in for a discount).
The chairs are comfortable, food selection is good - hot and cold food (even fruit) and there's drinks. Wifi uses the terminal wifi but the speeds are passable as long as you don't download anything big.
Beer drinkers might be a little disappointed though. I couldn't find beer, but there was a good selection of spirits and soft drinks to mix up your own - vodka lemon iced tea FTW ;)
