I'm assuming you're in california, so am I.
You drive down to the border, park at the largest lot, just on the other side of the small bridge (southish), and walk across the border. Take a taxi, to Adaletia's or Chicago's, plenty of poon, prices can be negoiated. There's nice hotels nearby, or boom-boom rooms upstairs for a small fee. Sometimes you have to pay a "bar-fine" because the girl works for the bar.
When you're done, have a taxi take you back to the checkpoint, where you'll have to walk back through inspection.
You Might need you DL.
Or you can walk down Avenuda Revoluction. Find the red bus, a couple bucks and right back across you go. Go with friends, it's more fun. Bring your own condoms. And if you get a short time room, leave a dollar for the clean up guy, it's good manners.
Tipping of the ladies is not expected, but they like it, a lot! And make sure you lay out the rules, things you want to do before you go back to the room.
Think with you big head, don't pick out the first girl you see, unless it's a short time, hang a little, enjoy the show. If you speak spanish, all the better.
I don't, so sometimes it's a pain, and I wait for a girl who speaks a smattering of english.
Oh yeah, girl drinks, cost double!!! And they get a kickback, so that's why they're pushing for drinks.
