Honk Kong has a great airport. You just enter Terminal 2 and are greeted with the sprawling SkyPlaza, which, in addition to the check in counters for this terminal, is full of stores, entertainment establishments (including an IMAX movie theater always showing one of the latest box office hits), and restaurants. You can easily while away a few hours here without even realizing it. Once you're done in terminal 2 (if you're flying with one of the few airlines that have check in here, then once you've checked in), head over to Terminal 1 (to check in, for most airlines) and to pass through security and customs (for all airlines, no matter in which terminal you've checked in). After you get past security/passport control, you'll have plenty more stores to visit -- and these are duty-free, unlike the ones in Terminal 2. If your plane is boarding at one of the farther gates, keep in mind it may be a 20-min walk (or even more, depending how fast you walk), so keep that in mind while shopping so you're not late for boarding.

Having travelled to a few airports in my time, this one is no different in fact many expensive watch, clothes, cosmetics and clothing shops. It's clean but is always hustling and bustling as you'd expect Still if you have an hour or two to waste you could do worse...
