This road is a popular bar-hopping and clubbing area. If you want to experience Patong's vibrant nightlife, this is the place to go. Some of the best clubs are located here. You have to pay an entrance fee to some of the discos, but you will get a drink voucher in exchange. Mind that many girls here try to lure male counterparts to join them.
