Other options to date young and not empty head women could be sneaking in at the Malba events, Centro Cultural Recoleta openings or Cine Gaumont. Try specific social networks like match.com or tagged.com, where on your profile you post your requirements and you look at her (updated) picture, and go through her profile before saying hi. And you chat on line (interview if you wish) before going out, so you dont lost a lot of time on a date with a boring woman.
As a not "empty head" young and single Argentine woman..I agree with Roxana, Malba is a great option, I loooove Malba!!
I would also suggest you try getting into Couchsurfing.org (not a dating site, but you can meet great people at the different weekly meetings)..
You can also find "us" in different classes..try maybe salsa or Rock lessons, language classes or different cultural activities. there are plenty of free activities created by el Gobierno de Buenos Aires on monthly basis..
I´m not a big fan of dating sites..not my cup of tea..but I guess it´s another tool to explore..
There are also Quiz nights in La Cigale and other places..
I´ve been to Spanglish a few times but I found the "speed dating" format a little boring after a few times..
Maybe a stroll around PAlermo? Palermo Lakes??
I´m running out of ideas..
And please..not EVERY Argentine girl is histérica or possesive or crazy...
Not every english guy is charming, altough I reckon I love their accent..
And so on...
People are people
Good luck with your quest!!
