The choices for shopping in Bangkok's Pathumwan District are simply staggering, and you will need a full day, if not more, if you want to cover all of them. Almost all of Bangkok's most famed shopping malls and department stores are located here, and they are all centrally located making it easy to navigate. The most famous and extravagant of them all are the Siam Paragon Mall and Central World Department Store, both of which house every famous fashion and designer brand name, not to mention endless restaurants, multiplex cinemas, and plenty more (there are even hotels located in these malls!). If you want the upmarket experience without the crowds, the elite Gaysorn Plaza across the street from Central World features only the uber-luxury items and shops. Joining it is the new Central Embassy, which has an innovative architectural design, and will soon house a 6 star hotel to go with its upmarket shopping options.
More mid range choices include the newly relaunched Siam Center and its neighbor Siam Discovery, still featuring tons of luxury but just not quite as glitzy. Stepping down a notch, MBK down the road is a great place to buy mobile phones, and if it is computers or just about any kind of electronic equipment you want, head over to the famed Panthip Plaza IT mecca, but do be aware of the pirated software here.
For a completely unique Asian shopping experience, head to the street stalls and alleyways of the Pratunam Market, where you might have to fight the masses for space, but it is colorful and certainly inexpensive. You have plenty of options here, and use this 10 Best guide to make the most of your time.
