The 2 best strip clubs IMO are: LeGrillon and Pantera Rosa.
The others (that Chili mentioned) can be good too but the talent level is generally lower in my opinion. There are usually a couple of lookers in these places but there are many at LG and PR. If you enjoy the hunt (going from place to place) you should check them out. Either way, you should always check out all of them and then pick the ones that fit.
LG is my fave, I haven't been to PR in a while. LG is gringo friendly (meaning they don't gringo gouge, the prices are posted, they have hot chicas for the most part, and the facilities are comfortable)
Be aware that the areas where both LG and PR are located are dangerous, so take a taxi directly to the front door and get the taxi at the front door. Don't get dropped off or walk to the corner to get a passing taxi to save 1K. Take the one parked in front of the club, it'll be 2-3k to get back.
Places to avoid are Tango India, Hollywood, Elite (I think they changed the name to protect the guilty (all clip joints.. think $300 "champagne" room)
