Güerrín

Güerrín has been feeding porteños from its corner on Avenida Corrientes since 1932, making it one of the oldest continuously operating pizzerias in Buenos Aires and a landmark of the city's distinctive pizza culture. Located at Av. Corrientes 1368 in the Centro, the restaurant occupies a corner position that has become iconic: its brightly lit windows, counter-service model, and perpetual queue of regulars eating standing up are as much a part of Buenos Aires street life as the tango halls and bookshops that surround it on Argentina's celebrated theatre avenue.

Buenos Aires pizza is a style unto itself — thicker than Neapolitan, richer than New York, and built on a tradition of Italian immigrant cooking that evolved over a century in the Río de la Plata basin. At Güerrín, the muzzarella slice is the benchmark: a generous wedge of thick, doughy pizza topped with a thick layer of stretchy mozzarella, cut to order and eaten standing at the counter. Equally iconic is the fainá — a slice of chickpea flatbread baked in wide round pans that Genoese immigrants brought to Argentina. Locals typically order both and eat the fainá alongside the pizza slice, sometimes sandwiching them together in a practice so widespread it has become part of Buenos Aires eating culture.

The whole pizza, sold by the half or full circle, is worth ordering for groups; varieties range from the classic muzzarella and fugazzeta (caramelized onion and cheese) to seasonal specials. Prices are low by any standard, making Güerrín accessible to every budget. The atmosphere is deliberately democratic — no reservations, no dress code, and no pretension. The restaurant is busy from mid-morning through the early hours, peaking after theatre shows let out from the many venues along Corrientes. Sit-down tables at the rear of the restaurant are offered at a slightly higher price than counter slices, reflecting the distinction between the quick eat-and-go format and a seated meal.
