If you do not want to have a bad night, do not go to club Blue in Medellin. Although the music is rock, this music is more what you want to listen to, not dance to. Additionally, the DJ should know better than to play 3 Killers songs in a row, followed by two kelly clarkson songs in a row. That is just lazy. The place was busy, but no one was dancing. This is a place to which overeager tourists travel looking for a good time, but neither drink nor company can augment the horrible atmosphere that club Blue creates. Avoid at all costs for other clubs in the area.
Dress Code: None.
The Parque Lleras is packed to gills on weekends with locals who come here to numerous bars and discos. And even during the week the restaurants are full and the place is buzzing with activity. The most popular discos here are Blue and Folia, but if you visit one and feel like changing atmosphere, another club is literally half a block away.
Dress Code: You can't overdress in Colombia.
Every resident of the city will tell you that this is the most upscale club in their city, and it certainly will not disappoint. The music is a mix from hip-hop to salsa, waitstaff is dressed in cowboy attire, entry is $15,000 pesos. The place is more like a large bar, as there is no dance floor per se, and everyone is dancing between the tables. There are numerous performance acts that are superbly executed. Quality of women is extraordinary, and might take your breath away ;)
The only drawbacks are that it is located very far and that it appears to attract shallow people with a drive to impress each other (which is inescapable with any upscale club). Nonetheless, you will enjoy every minute you spend here.
Dress Code: You can't overdress in Colombia!
If you like to spend $ and see midgets, go to Mangos. It´s the hot place. Club Blue is 5000 to get in ($2.50) and includes 2 beers it´s a standard club.
If you want to go to a hole in the wall Salsa club with great atmosphere try Tibiri. No sign, just stairs to teh basement. It´s on Street 70 and 48D? I think. It´s known as a dive with the best music.
Dress Code: Mangos you can´t wear sneakers
According to taxi driver (and as always, they are the best source of information) Mango's was the place (it was in 03/2005) so I went there on day of carnaval.
Big and lively place.
Alternatives are in Zona Rosa, but those are more like eating & dancing places.
Dress Code: smart casual
