Argentine-Italian celebrity chef Donato di Santo has led somewhat of a revolution in Argentine cuisine—pushing always for the simplest and freshest take on traditional Italian cooking. Try his food at this lively, casual deli-grocery store in Palermo (there's also a second location in the Belgrano neighborhood). Stick with the stuffed pastas or the daily specials. It’s open all day, so stop in for a coffee with an exquisite pastry in the morning, or an aperitivo with a nibble on the side in the early evening.
