Soi Pratuchai is a gay related entertainment walkway in the Bangrak district of Bangkok, Thailand, catering mainly, though not exclusively, to foreign tourists and expatriates. While Soi Pratuchai is internationally known as a red light district for gay at the heart of Bangkok's sex industry, the city in fact has numerous gay related red-light districts that are far more popular with Thai. It consists of a “7” shape walkway running between Surawong Road and Rama IV Road. Soi Pratuchai is within walking distance from the BTS Skytrain Silom Line's Sala Daeng Station, and MRT Bangkok Metro Blue Line's Si Lom Station.
Most Soi Pratuchai go-go bars feature boy dancing on a stage. The dancers (and even occasionally the serving staff) are generally available to customers willing to pay a bar fine to take them out of the bar; the fees for sexual services are negotiated separately. Some establishments advertising "massages" are in fact disguised brothels, and a few famous "blowjob bars" offer oral sex at the main bar or in back rooms.
Several upstairs bars still feature (technically illegal) sex shows, with boys performing various creative acts. Perhaps the most notorious of these features boys performing exotic feats involving bathing. Some of these second-floor gay bars are run by scam artists who lure tourists with offers of low prices and later present a wildly inflated bill along with a threat of physical harm should the bill go unpaid. The Tourist Police, usually stationed at Patpong 1 and Silom Road, can help in these situations.
