Patpong is on again (or was)
I visited the gogo-bars in Patpong 1 and 2 recently (November and January), is seems that there are some improvements since my last visit in this area (2012). Although some say that the bars were better one year ago. Some details: Patpong 2 is the best, the bars Electric Blue, Bada Bing and Pink Panther (and maybe Black Pagda) made the best impression with me. In Patpong 1 only Kings Castle 1 is worth a visit. Stages full of stunners, no drink pressure, and the girls are friendly to chat with over a drink. Note that not all of them barfine, and some are coyote dancers. Drink prices are mostly 120-140 and LDs 200, so the same as in the other two gogo-areas. But some bars have draft beer for 90.
I found a really cute girl in Electric Blue, very little English spoken though. 2500 for st and 4000 for LT. But the barfine is 1000, I found that a bit strange since it's usually 600.
Anyway, Patpong is an interesting alternative if your tired of Nana and Cowboy. Sala Daeng Skytrain station, exit 1. Or Silom MRT station, but then it's a longer walk through those silly night markets.
