The bargaining block where Pratunam's indoor transactions take place is consisted of three major shopping centers: the Bai Yoke Garment complex 1 & 2, which has wholesale deals on garments; Indra Square, has fashion clothing and accessories for men and women, along with silk items, jewellery, and touristy Thai crafts; and the City Complex, which also offers fashionable clothing marketed towards young ladies, plus a few shops selling jewellery and crafts. Also in the Pratunam area are several top-notch hotels to make your shopping experience more convenient.

Outside and between the complexes vendors and small shops sell shoes, t-shirts, 'brand-name' items, CD's, and various knick-knacks. Food vendors push their way through the large crowd to hawk the usual fruit and scewered foods; if you're hungry and need a rest, there's a food center on the second floor of Indra Square. This area can become quite hectic with pushy pedestrains, so come with a patient attitude and, if possible, well-rested. This is also a wise investment, as a smile will usually knock off at least 10 to 20 baht from the asking price.

How to get there: From BTS Siam station, take the Skytrain one stop towards Mo Chit to Ratchathewi station. From there, exit down the right-hand stairs, take a right at the next main intersection and walk down Phetchaburi until you see Platinum department store; the market is directly across from Platinum Fashion Mall (total ten to twelve minute walk). Or just take a tuk-tuk or taxi from the station to the market.
