I had a last beer on the car park (1 heineken for 80 B) after 2 AM when bars are closed. The girl opened my bottle and gave me the change. I remember sitting on Golden's steps and drinking my beer but I cannot recall what happened just after that. I waked up in my room, alone, with an empty wallet (I had about 4000 B in it). I probably have been druged so, be really careful and avoid buying beers in the street in that area (or a least, open the bottle yourself)
Soi Zero does not exists anymore. A new bar area (looks like Soi Sukhumvit in Phuket) has oppened on the other side of the road, near Ploenchit station.
