What makes People Lounge different is that it is different. An original theme, modelled on a New York theatre bar. Unapologetically retro music. Great location. If you're 30+ this should be on your itinerary.
Botànic Bar Cafè is a great place for a quiet drink with mates (in the back garden) or a loud drink with strangers (inside). Central to all the action and does food too!
El Berro is a great choice of restaurant. It's in the centre of the gay scene. It has great food, a fun atmosphere, it's reasonably priced and it has unusually fast service!
Culture Club is a relatively new bar which has quickly earned a place in the gay scene of Barcelona. Friendly atmosphere plus a giant dance floor downstairs.
