Sukhumvit (Thai: สุขุมวิท) is an exclusive district in Bangkok. It is home to fancy apartments, villas, restaurants, bars and clubs. Popular among foreign visitors and expats, it becomes more and more a Thai residential neighbourhood as you follow the road southeast. Khlong Toei is also dealt with here, which, by contrast, is one of the poorest neighbourhoods of Bangkok.
The lowered-numbered sois (roughly between Soi 1 and 63) are a popular residential area for western expatriates and affluent Thais. It is densely packed with shopping centres, restaurants and hotels. The fleshpots of Nana Entertainment Plaza (in Soi 4) and Soi Cowboy (between Soi 21 and 23) are also in this area, as are plenty of more (and less) salubrious bars. Also, the pavement of Sukhumvit itself has become a huge market carrying everything from luggage to fake Rolex watches, and after midnight they turn into roadside bars and pubs. Sukhumvit offers the best dining in Bangkok, from five-star dining to street stands, the variety of choices and tastes are almost overwhelming. Japanese nationals can be found in the area Soi 21 and upwards, but most tend to congregate around Soi 55. Indians have settled around Soi 12, while Arabs are grouped at Soi 3/1, which informally is known as Soi Arab. After Soi 63, Thais take over again, though this might change when the Skytrain extension is completed in late 2011.
Skytrain
The BTS Sukhumvit Line runs, as the name suggests, over Sukhumvit Road from west to east. Sukhumvit can directly be reached by Skytrain if you're coming from Siam Square or Phahonyothin. A ride from Mo Chit takes about 25 minutes to reach Asok station, while a ride from Siam station takes about 10 minutes. If you're coming from Silom, you'll need to take the Silom Line north and change onto the Sukhumvit Line at Siam station. It takes about 20 minutes for a ride from Saphan Taksin station to reach Asok station, including the transfer at Siam. Trains leave every five to ten minutes for a fare of about 15 to 40 baht.
