Within big-city Buenos Aires, San Telmo maintains its familial appeal; neighbors wave hello to one another from cobblestone alleyways, as regulars fill bars and restaurants inhabiting former belle époque mansions. Hit the streets on a Sunday to browse the open-air antiques stalls of Feria de San Telmo. Discover San Telmo’s newest eateries within the 120-year-old Mercado de San Telmo, ranging from Vietnamese street food at Saigon to French pastries at Merci. Of course, you’ll also want to sample some Argentine staples, so seek out Los Infernales for chorizo sausage sandwiches and El Banco Rojo for the city’s best lamb empanadas. And to savor Argentina’s famed Malbec along with lesser-known but equally worthy wines, head to Pulpería Quilapán, a bar and general store that often hosts live music and garden vinyl parties.
