From the glittering high end department stores such as Emporium or Siam Paragon where the beautiful people get a fix of genuine Gucci and Armani to the bustling crowds of Pratunam where traders from all over the world jostle to buy in bulk and pile it high.
For those staying in the tourist areas of Silom or Sukhumvit the place to start is just a short walk from your hotel. At night the lower end of Sukhumvit is lined with stalls selling clothing, DVDs, handicrafts, bags, furnishings, watches and jewelry. Bargain hard because the vendors will often test your knowledge by asking an absurdly high price at first. The night market around Silom and Patpong is even more hard headed. The traders here only get about four hours of selling time each evening and the rents are high so they will try hard to get overly high prices from those who, maybe, have just arrived. It is worth taking your time to look and ask before you start bargaining. Don't be afraid to set your starting price at a third or a quarter of the asking price as long as you do it with a smile. There are some excellent goods to be found however. Household furnishing in traditional styles and clothing can be some of the best deals.
