Denmark is one of those countries where citizens are deliriously happy all the time, at least according to surveys conducted by someone.

Sometimes I dream I'm living in Bangkok's Chinatown, a Chinatown like no other that I've been to. It's enormous, and every night it's packed with people who are mainly there to eat.

Like San Francisco and New York City, food trucks are big in Tokyo. Well not exactly big but tiny in fact.
