Here are the photos showing Petaling Street at Kuala Lumpur. Its also call Chinatown among local citizens.
You can get cheap and nice food here and also cheap to shop here. The walking past of the Petaling Street is like a t shape, which might confuse you. But its alright cause there too many things to see here and it will take your whole night time of fun here.
My only advice, is to wear simple clothing like casual t-shirt and shorts cause it humid with the crowd there.
