At the CX lounge in HKG now, the one called The Pier (CX has two lounges in HKG, the other called The Wing). As far as airport lounges go, the CX lounge in HKG is the best in amenities and food. Top marks for design, though, goes to the TK lounge in Istanbul with its palatial interior design.
The food in the CX lounge in HKG is superb, complete with a Noodle Bar where you order freshly cooked noodles. In no other lounge have I seen freshly cooked food; usually the main course is a bunch of cold sandwiches and soups kept on warm. For this layover, I got the following: wonton noodles, spring rolls, fried rice, sausages wrapped in bacon, vegetable tempura, and a fruit plate. And before you start making aspersions about my appetite (which, if you know me, are not necessarily off the mark), the serving sizes I got were very small, like a piece or two of each dish. So, no, I'm not about to burst with all this free food.
Next stop, SFO.
