According to AOL travel site and a CNN post, Orchard Road, Singapore is the best shopping avenues followed by Avenue de la Liberte, Luxembourg and PC Hoofstraat, Amsterdam.

Orchard Road in Singapore is claimed to be the cleanest, most welcoming and most friendly shopping avenues in the world. There are twenty two shopping malls and six department stores on Orchard Road, so you have plenty choice and won't be able to check every shop in just one day.
