The Patpong area is famous for its bars, neon lights, girls, sex shows, and massage parlors, but it also hosts a bustling Night Market along the central streets (hemmed in on all sides by go-go bars and sex-show clubs) that sell mostly faux brands: pirated CDs and tapes, designer knockoffs, copy watches (including fake Rolexes that I've gotten some good reports on), leather goods stamped with desirable logos (sure to hold up better than cardboard) -- not especially cheap, but lively and fun, especially if you enjoy crowds and the challenge of hard bargaining. Open daily after sundown.
