Editor’s note: This is the penultimate installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. Stay tuned for our final “Best Bites” dispatch, from Istanbul, tomorrow. Restaurant Roma We hadn’t planned on bringing in La Nochevieja at Restaurant Roma, but it was nearby and we didn’t feel up for public-transport adventures on New Year’s Eve. Situated on a quiet street in the upscale but untouristy Barcelona neighborhood of Sant Gervasi, Roma is thoroughly nondescript – a neighborhood joint frequented by neighborhood people of a certain age. The wood-paneled walls, racks of Maxim magazines and TV mounted in the corner kept our expectations pretty low.
