1. Sukhumvit – The long Sukhumvit Road, changing name to Ploenchit Road and Rama I Road going west, is Bangkok's modern commercial core, full of glitzy malls and hotels. The Skytrain intersection at Siam Square is the closest thing Bangkok has to a centre.
2. Silom – To the south of Sukhumvit, the area around Silom Road and Sathorn Road is Thailand's sober financial center by day, but Bangkok's primary party district by night when quarters like the infamous Patpong come alive.Suriwongse Road -The Entrance to Patpong road and the gay paradise opposite to it.
3. Rattanakosin – Between the river and Sukhumvit lies the densely packed "Old Bangkok", home to Bangkok's best-known wats. Yaowarat (Chinatown) and sights around the Chao Phraya River are also included here. Bangkok's backpacker mecca Khao San Road and the surrounding district of Banglamphu are located on the northern part of Rattanakosin.
4. Thonburi – The quieter west bank of the Chao Phraya River, with many small canals and some offbeat attractions.
5. Phahonyothin – The area around Phahonyothin Road and Viphavadi Rangsit Road is best known for the Chatuchak Weekend Market and Don Muang Airport.
6. Ratchadaphisek – The district north of Sukhumvit centered around Ratchadaphisek Road (part of which is called Asoke) and reaching from Phetchaburi Road to Lat Phrao. This area has really opened up recently as the new metro line follows Ratchadaphisek Road.
