Note that Soi Bangla, Soi Cowboy and Soi Patpong 1 & 2 are all privately owned and not public throughfares. Walking Street is dominated by bars and bargoer establishments (rest. etc), so little resistance, I suspect. Most don't know, but Soi 4 has a very large residential community further down as well has some Thai high rollers who would not be amused! Glass
