Patpong is a strange place . I remember it being lively in the early 80's but now it is just for tourists and shoppers. For those on a sex trip I recommend care if you go to one of the upstairs bars.
If you are buying stuff check out the prices elsewhere, Pattaya, Chiang Mai will be cheaper.
Fun Alternatives way too many markets to mention . (the weekend market has been spoilt with the arrival of the skytrain and metro).
for sex travellers try the areas off Sukhumvit
HAVING VISITED PATPONG NIGHT MARKET SEVERAL TIMES OVER THE YEARS AND MOST OF THE TIME ENJOYED AND GOT SOME BARGAINS.I WAS DISSAPOINTED JULY 2007 WITH THE MARKET TRADERS STARTING PRICES HAVING KNOWLEDGE OF WHAT A WATCH, BELT,T SHIRT ETC SHOULD BE SELLING FOR THERE STARTING PRICES WERE TO HIGH AND VERY DIFFICULT TO BARGAIN DOWN TO A FAIR PRICE.
Unique Suggestions ONLY NEGOTIATE FOR AN ITEM WHEN YOU REALY WANT TO BUY IT. THIS WILL SAVE YOU A LOT OF WASTED TIME
Fun Alternatives IF YOU ARE IN BANGKOK AT THE WEEKEND MO CHIT WEEKEND MARKET IS THE BEST MARKET I HAVE SEEN IN THAILAND MUCH BETTER PRICES ALL THE LOCALS SHOP THERE.
