Rambla Nova contains a handful of sleepy-looking bars, any of which will serve a cup of coffee or bottle of beer throughout the day and evening.
You might try the cafe-bar Pla La Seu, Plaza de la Seu 5 (tel. 97-723-04-07), which lies close to the cathedral. You can sit outside enjoying a drink while taking in the facade. In summer live jazz is presented on Saturday and Sunday. Live bands often appear at the aptly named Scum, Fortuny 22 (tel. 61-595-94-13), which generally features a dozen concerts a month. An older crowd (that is, in their 20s and 30s) sometimes get raucous as the night wears on. Expect to hear blues, jazz, rock, soul, whatever.
Concerts and theatrical productions are staged in the city's cultural centerpiece, Teatro Metropol, Rambla Nova 46 (tel. 97-724-47-95). Because of the language barrier, you might skip theatrical events presented in Catalan in favor of musical and dance presentations.
