Bar Pinotxo is arguably La Boqueria's, and even Barcelona's, best tapas bar. It sits among the half-dozen or so informal eateries within the market, and the popular owner, Juanito, might serve up chickpeas with pine nuts and raisins, a soft mix of potato and spinach sprinkled with salt, soft baby squid with cannellini beans, or a quivering cube of caramel-sweet pork belly.
