I've recently spent all summer updating a guidebook about the nightlife in Barcelona and loved exploring the eclectic and cramped local bars of Gothic Quarter and El Born, the trendy joints of the shabby chic district of Raval ... as well as the swanky lounge bars and clubs on the beach by the Port Olimpic.
I've distilled my research (over 70 places visited!) into one article for Barcelona Life (www.barcelona-life.com), and I hope it helps people make the most of the nightlife scene here...
Pasalo bien!
