If you want to learn salsa... and pick up girls at the same time. The easiest way is at happy hours that feature basic lessons. But you will never get past basic skill level there. Here in DC(which is shitty place to game) the girls are normally nervous in the first few dance classes, and so they drink more than there usual... to get over the anxiety. I have been told by so many chicks while we were dancing that... "I had to take two shots just to get myself out on the floor to try this."
It is so easy its ridiculous.. I actual got bored of this scene.
Also,
The site below is a good place to start: They have alot of great youtube videos. Find any chick you want and say that she can be your partner(like its a privilege) ... And she will be so down to come over your house and practice (especially ones with boyfriends.. which i cant understand). I always say, It's like putting chickens in a cage with a tiger... YOU WILL INCIDENTALLY CONVERT HER.
This is the site. It's great for tutorials:

Also, a good line for when they asked you where you learned to dance.... I say "youtube". The always breakout laughing..
But, what i found that is a big key(with Latinas specifically) is... Dancing the style, based on where there from.
If she is cuban... casino style salsa.
If she a Boricua, tradition "on-1" style.
Colombian... "The Cali style"
Colombians swear that people from Cali Colombia or the best in the world(So dance there style with a colombian).
New York Latina.. Dance "on-2".
Mexican or west coasters... LA style Salsa.
For Bachata, I've noticed if you can dance both the Dominican style and the traditional style side to side style, girls are always impressed.
Obviously Dominicans are because, its there style... and other latinas are because they just assume that you're on a level above there skill. Check out this Dominican Dudes videos, You can learn alot by just watching... honestly.

Its funny because that chick is another popular dancers wife... But If you notice her body language when she tried to lead him(instead of letting the man lead) and he pulled here hard(to put her in her place), she became submissive Immediately. She was wet right then and there. Watch her face and body language. It's just funny to me. Then watch her with her husband dancing she has an almost uninterested disposition. I would be willing to bet this dude banged her, of if not he could.
Also, if you notice he always dancing in a way that makes her advance to him as he moves away and steps back. Almost Like she is chasing him. When you do this, it send some sort of signal putting them in that mind set to chase you. I have had girls, (That I know would not have gave me the time of day) follow me out of clubs, to ask for my number.
Learning to dance has been my single most effective investment.
I will post videos of each style if anyone is interested.
