Have you been?! I went last year, it’s really good. It’s at La Rural near the Palermo Zoo in Buenos Aires.
Imagine a convention center filled with seven large isles of locals selling their own creations. The main attractions are- artisan cheeses, cured meats, dulce de leche and unusual amazing potatoes. There are A LOT of vendors and it’s super organized and well done. They even have gardens full of lettuce and other leafy greens.
