Think of it not as a trek to the less-than-central neighbourhood of Nou Barris, but as a quest; queues outside are testament to the great value of the tapas. On especially busy nights you'll be asked to take a number, supermarket-style. Waiters will advise first-timers to start with 'chocos' (tender battered squid rings), patatas bravas with alioli, 'llonganissa' sausage and 'tigres' (stuffed mussels). After that, the world is your oyster, cockle or clam.
