Been here a few times throughout the years. Its floor upon floors of wholesale clothing apparel for sale. The best thing to get here is the batik shirts which are quite cheap.
The whole building is separated to different floors and each floor specialises on something for the family. A floor might just be all of kids' clothes; another would be men's clothes; and another would be women's clothes.
As it is wholesale therefore they don't sell individual items, you need to buy at least 3 so better if you come with friends.
Always bargain and don't buy the first thing you see, the chance is there is another shop on the same floor which sells it cheaper.
This place can be very hectic near the school holidays, therefore always look after your belongings. Better to leave the kids at the hotel rather than take them here during the peak hours.

To describe the place, it's like Chatuchak market in Bangkok, housed in one place. and everyone is squeezed in here. If you love a bargain, and willing to bump into the locals, this is a good place for buying batik shirts, t-shirts, kids' clothing,ladies bags, shoes, etc. Do dress conservatively, no short shorts and spaghetti tops pls. Otherwise, you will feel uncomfortable. Keep your moneybag with you safely, as people do jostle around. Toilets facilities are on every floor.
Remember to bargain for almost everything.

Good place to find wholesale mainly clothing & quite cheap...about 7 or 8 storey high and there is a mosque on the high floor...
