Visit the backpackers' Mecca constructed in 1892, where the tourists from all over the world come for the nightlife, shopping and dining experience.
It is a must-see for its incredible buzz where you can not only enjoy the diversity of tourists and observe the everyday interactions of locals during the day but also visit some of the city's major bars at night. The stalls offer a great variety of food though everything is slightly overpriced due to the road being one of the major tourist attractions. It gets quite busy though so be prepared for crowds of people and vendors trying to force their products onto everyone who looks like a foreigner.
