Buenos Aires Pizzeria features the full spectrum of Argentine immigration in pizza form, but Francis Carrera's Buenos Aires Grill goes much deeper, offering perfect renditions of many of the international plates that have fed generations of Buenos Aires residents and shaped the cuisine of that city. The focus at this lovely restaurant is definitely meat -- a churrasco board dominates -- but so many excellent plates can be found hovering around the edges of the menu that one meal here just leaves you wanting more. The blood sausage is the best we've ever had, the bacalao (salt cod) an upscaled version of a peasant classic, and almost anything coming off the grills tastes of a deep cultural understanding that's rare in even the most rigorously authentic ethnic restaurants.
