I live in Valencia so should be able to give you a couple of pointers. The main bar/restaurant areas are El Carmen, Canovas and Ruzafa. All zones highly recommended although bars playing good music are a bit thin on the ground, it's usually Spanish commercial pop music. There are a few clubs: La3, Mini Club, Umbracle are all popular but check thier respective websites to see what type of music you can expect.Ok I'm guessing things have changed in 8 years or so, but I'm going in a few weeks.
Are there any good areas with good bars or clubs worth visiting?
Any tips welcome!!
