Siam Square sits at the heart of Bangkok's Pathumwan district. An entertainment, shopping and educational area packed with restaurants, cinemas, and hundreds of shops -- if you've got time for just one shopping excursion, this is where you should be heading.

One of Bangkok's top shopping districts, Siam Square itself overflows with retail outlets where designer boutiques abut knock-off shops and fancy dining sit side-by-side with street-side eateries. The area is particularly popular with students, as Chulalongkorn University makes up the southern border of the neighbourhood and this popularity is reflected in many of the student-orientated stores.

The area is also home to a number of Bangkok's top shopping malls from the more low-brow MBK Centre, where cell phones, clothes, and furniture are the primary wares, to the increasingly more upscale Siam Discovery, Siam Centre, and Siam Paragon, where Lamborghini and Ferrari dealerships sit beside Prada and La Perla boutiques. An above-ground walking path beginning at Siam BTS and connecting to Chit Lom BTS allows you to stroll past a number of other shopping and hotel complexes including the recently refurbished Central World Plaza.

Siam Square is also home to the greatest concentration of Bangkok's cinemas, including Scala, one of the few old-school wide-screen theatres, Lido, which screens independent films, and Paragon IMAX. Movies are much cheaper in Thailand than in the west, but remember to bring a sweater as they tend to be highly air-conditioned, and don't forget to stand when they play the anthem for the King.

Heading east, the main throughfare of Rama I becomes Phloenchit Road, off of which Sois Ruam Rudee and Lang Suan run. These are famous for their food and entertainment spots, although some are in danger of being replaced by condos in the near future. Further south lies central Bangkok's largest expanse of greenery -- Lumpini Park -- a leafy reminder of what Bangkok could have been.

North of Siam Square is Pratunam -- another of Bangkok's major shopping areas, with a bustling wholesale clothing market in the shadow of Bangkok’s tallest building, Baiyoke Tower.

Traditionally a cloth and fabrics warehousing and trading area, Pratunam's offerings have expanded considerably over the years and today, thanks to the likes of new-on-the-scene Platinum Mall and the nearby software heaven Panthip Plaza, you can get everything from pirated software to a new laptop and fake Gucci handbags to US$5,000 suits.

Further north again lies Phayathai, centred around the landmark Victory Monument, which was built to honour the Thai soldiers who have died defending their homeland. Although a popular shopping area for students, Phayathai has little of interest to the overseas visitor other than one landmark bar and a unique restaurant.

North again brings you to Ari BTS station which services a relative newcomer to Bangkok's trendy art scene. Much like the J-Avenue area of Thong Lo, Ari has become a haven of artistically minded Thai's, although it's less developed and therefore a bit more subdued. Originally well known for its concentration of excellent Thai food, Ari has seen the introduction of a number of Thai chain eateries, as well as a few hip new cafes, bars, and hotels.

Characterised by heavy traffic, congested pavements and mid-range hotels, all these areas are permanently teeming with people.
