Singapore is one of the world's richest cities, with a standard of living to match, and in recent years it has moved on from its image as a sterile, overly officious nanny state to become one of the most dynamic and exciting cities in the region. Singapore's heritage as an important trading post means that there is a real cultural mix, with four official languages: English, Chinese, Malay and Tamil. Step away from the gleaming towers and you'll find yourself transported into another world amongst the intoxicating streets of Chinatown and Little India.
