We entered Patio Olmos shopping centre to escape the heat of the city (middle of January) and we found a real bargain: the Black Grill Restaurant Fast 11. It is located on the second floor (Local 314), in the food court. It has very good meat at incredible prices, including two side dishes! In Buenos Aires, you can not find a steak or sausage for these crazy prices. We returned whenever we could, spectacular!
