To help those who are following the thread and trying to figure out what club has what:
El Palacio Gaviria : has several different rooms and plays a variety of music: salsa, another where its dance music and at least one other where its different music. I also think what they're playing depends on the night you go. Its big hit with foreigners because it does an international night for people to meet... so you find everything. (its cool to go at least once, as it use to be a Palacete, and when that use was done, even a market- but that part you wont see, its roped off and behind a curtain when you go in- the rooms however, except nix the furniture, are pretty much what they looked like when it was a palacete- pretty cool!
)
Joy : dance dance dance. 2 floors... its a converted old theatre- and you can tell by the setup. the 'upstairs' are what used to be the balconies- most of it is on the ground floor.
Kapital : several floors with different music. Mostly dance, with a floor where they play Spanish favorites and yes even a floor where its nice and calm where you can sit down and talk without having to scream at the person you're talking to.
Joy and the Palacio are huge with foreigners- Kapital has its share, but not so much in comparison to the other two clubs...if you're looking for something more Spanish and want the upscale (expenisve or as we say in spanish Pijo) thing, then go to the Avenida de Brazil area, or Serrano, where the clubs are smaller than the three mentioned above, but larger than the typical disco- and less foreigners (if you're looking to mingle).
This woman is seriously looking for a legitimate dancing job!
