Mercado de San Telmo
970 Bolívar, Comuna 1, Buenos Aires, B1704, Argentina
Mercado de San Telmo is a covered market from 1897 that has evolved from a traditional neighbourhood food market into Buenos Aires' most exciting food destination — a cavernous iron-and-glass structure housing butchers, produce vendors, coffee roasters, wine bars, and the new generation of food stalls that have turned the market into a culinary crossroads where traditional Argentine cooking meets global influences.
Reserva Ecológica Costanera Sur
Avenida Costanera Doctor Tristán Achával Rodríguez, Comuna 1, Buenos Aires, B1864, Argentina

San Telmo
1 Defensa, Comuna 1, Buenos Aires, B1718, Argentina
San Telmo is Buenos Aires' oldest residential neighbourhood — a district of colonial-era houses, antique shops, tango bars, and the famous Sunday market that transforms Defensa Street into a 10-block open-air bazaar of antiques, crafts, street food, and tango performances.
