I just returned from PV, where my girlfriend and I spent 3 evenings in attempts to find a salsa scene. It appears not to exist. The Trip Advisor review published on 5/11/07 is still so spot on that it deserves to be repeated here:

"Cumbia and weird Rock and Roll Club

If you like salsa, cumbia, mambo, megrenge, J&B is the right place for you, the new authentic Cuban band is a guarantee of excellent music and plenty of fun. Tip, the band starts around midnight, dont go before.
