Airport food. It's expensive, it tastes dismal, and it does very little at all to sate the hunger of a weary traveller. Whether in Heathrow, Dubai, Incheon or Kuala Lumpur, all I usually end up with is an over-priced and over-frothed cappuccino.
But the best airport meal I ever had is this one. It doesn't look much, but man did it taste good! And for once, didn't cost too much either. The airport? Taoyuan International Airport, Taipei, Taiwan.
