I understand that this is a broad question, Santiago or Buenos Aires! We are a group of two couples traveling in January 2025, en route to Patagonia. We have a limited timeframe of 2-3 days and would like to explore one major city—either Buenos Aires or Santiago. Our focus is on immersive, local experiences, delving into culture and savoring authentic cuisine. We're open to venturing to the outskirts, surrounding areas, or even staying in a suburb or town nearby rather than being in the heart of the city. Our interests lie in beach experiences, historical sites, local culture, intriguing food, and connecting with people for unexpected encounters. Any suggestions for us to explore would be greatly appreciated! (I will also post this in the Santiago forum for additional insights). Thank you!
