For a taste of the untiringly tacky, touristy and downright bizarre side of Bangkok, look no further than Patpong. Immortalized in The Deer Hunter, the city's notorious red light district is also known for a bustling night market. Go-go bars and strip clubs jostle for attention amid designer knockoff stalls and a proliferation of men touting sex shows and adult DVDs. From dusk until dawn there's never a dull moment.
