Pizzería Angelín
Named for an Italian immigrant pizza seller who, per a first-person La Nación interview with his adopted successor's grandson Ramiro Pintos, sold pizza from a bicycle outside Buenos Aires football stadiums before opening a stall in 1936 and moving to the current Avenida Córdoba address in 1938. The pizzeria is now run by the third generation of the family that inherited it, and its pizza is still baked in a wood-fired oven, per the same article's photo caption.
