Las Vegas
Some girls hang out at the Masquerade Village Bar, the remainder hang out at Shutters Bar (AKA Hooker Bar). However, if this is your first trip to Vegas, may I suggest booking time with a well known provider say 4-6 hours and have dinner up at the VooDoo cafe. If you decide to try your luck down at the bars, the first night or two I would "window shop". You might wind up with the wrong girl and you'll have memories, an empty wallet, and sexually unfulfilled if you catch my meaning... 
That is the worst thing you can do and most likely they will throw the money back into your face. These guys are not going to risk losing their jobs and/or get arrested for "pimping" (which is a felony in Nevada). Working swing or graveyard as a bartender in a Strip Hotel is a highly coveted job which usually takes several years (most had to start as barbacks at the same hotel) and lots of "juice" (favors) just to be considered for the position.
Over time, you may earn the Bartender's respect and trust, but he will NEVER arrange/steer/recommend a date for you. As a "customer", you can expect 3 things from your bartender:
1) To serve you drinks
2) Listen to your life story
3) If you happen to catch "Raider Russ" working graveyard at Shutter's, he'll tell you 1,000,001 jokes - most of which are funny.
I'm surprised it did - but this is a public forum if you know what I mean...
As for Russ, he's off on Sundays and Mondays but I bet Max is laughing his ass off - unless he lost a bundle on the game. I'll probably see him this Thursday - hopefully by that time he would have gotten over it... but I wouldn't hold my breath ...
