Pura Tierra is without a doubt one the best restaurants in BA. It focuses on showcasing the best ingredients found in Argentina. With hefty weakly shipments from the Northwest region, this Buenos Aires gem cannot be missed. I had the opportunity to take a cooking class and learn about all the indigenous products that can be found here if you know where to go. Bottom line is, this restaurant is unmissable and Barrio Chino and Mercado de Liniers are crucial shopping areas for foodies.
