This popular street market has pretty much everything you can think of. It is lined with hundreds of stalls selling all goods imaginable. Don't be surprised if the items don't have listed prices - bargaining is a must here.
Apart from the usual items that you can get there (such as clothing, souvenirs, toys, various gifts, takeaway food, snacks etc.), there is a special section of the market dedicated to pets, called Goldfish Street. Goldfish are sold here in quite big quantities (either in small plastic bags or aquariums). Apart from fish, dogs, cats, and other small pets are also sold there.
The street's southern end is known as Ladies' Market - head here if looking for clothes, jewellery, handbags, or shoes.
The stalls open around 10 am and close around midnight.
