This place is a total ripoff.
We were offered free admission for ladies and $25 admission for guys by a promoter on the strip. Lyfred Sanico was the original promoter and JC Salvador was the one we were referred to to go to XS.
We got to the club early - 10:30pm. My boyfriend and I were told to stand on line and separate - guys from girls. I got in for free (nobody ever mentioned an additional cover) and he ended up paying $60 for admission to both the outside and inside areas. So we went in and tried to go inside to the main concert part, but were told that We cannot get in because I did not have an inside stamp, and we were redirected to several people before being told that we both need to pay additional cover to be allowed inside. So we went back to the general admission line and ended up paying $30 for me to get inside. Then we went back to the line to get inside and, long story short, we waited an hour and a half. Meanwhile, other groups (of guys and girls) got in immediately with no wait. I ended up getting really annoyed and leaving the line.
I guess this is how this place makes money - by ripping people off. Buyer beware.
