Silom Thai: สีลม is the closest Bangkok gets to Wall Street, with glistening skyscrapers all boasting the names of financial institutions. After nightfall the character of the place changes considerably though: the small sois between Silom Road and Surawong Road come alive with people out for a good time, including the infamous den of sleaze that is Patpong. The former trade quarter Bang Rak บางรัก is also covered here. It is home to many of Bangkok's top luxury hotels, including the Oriental.
