Late posting, last month I decided to try Elefante Branco. Went there around 10. 00pm. There were about 20 girls there. I suppose when you're "young" you tend to be looked favourably upon, as one girl I was interested in had an older man chat to her for a while but she rejected him. I gave her a wink and after he left, I started chatting to her. She was from Brazil but moved to Lisboa. She first said 200 EURO but I negotiated down to 100 EUROS. Rule of the club is that you got to buy a drink when you enter and also one for the girl before you leave. So add another 30 EUROS for that. She was curvy and decent looking about a 7. Out of the girls there only like 4 were doable ones but I didn't really check out everyone. I also paid $25 EUROS for a room next door from EB so yeah, costed me about $155 EUROS in total. She was really tight but quite passionate and I loved that!
I suppose if you want sex in Lisboa, Elefante Branco is the place to go as I haven't found any other places during my stay in Lisboa.
