VIETNAM, SAIGON: Most of the food I try in Asia, especially the street food, is excellent. But there's always the exception. This day in Vietnam was a horrible food day. After not having had a single bite of anything for 36 hours I decided to sit down at a street restaurant to eat a whole chicken. I was mighty hungry and looking forward to devouring it like no chicken I've ever dug into in my lifetime. So what was wrong with the food and why was it so bad?
