London
Not sure about the Bristol scene, but if you get a chance to visit London, Salsa in Charing Cross road is a good night, they usually have a live band on a Saturday night. Their website is
Salsa!, we were there on Saturday celebrating DR Independence Day, there a couple of videos and pics on our photo blog
Dominicanoenlondres. I've also heard that the food at
Cubana is really good, haven't had the chance to visit yet, but its advisable to book in advance, I hear it gets really busy. Enjoy your visit!!
