Pattaya has derived part of its reputation as a tourist destination due to the sex industry and the resulting nightlife, and this notoriety has influenced the city's evolution in many ways. Prostitution in Thailand is technically illegal but tolerated in most cities, including Pattaya. The city's vast numbers of host bars, gogo bars, massage parlours, saunas, and hourly hotels, serve foreign tourists as well as locals. This is especially prominent on Walking Street as well as other areas around the city. Efforts have been made to clean up the city's image.
