For me personally this restaurant is one of the best in the world when it comes to meat dishes (Parillada). We have been there on one of our fomer trips to Buenos Aires. If you have never eaten meat in Argentina you might think I am exagerating and that there is good meat everywhere. For me Argentina has the perfect combination of very good quality meat (from the pampa), big charcoal grills, few salt, pieces under 300gr don’t even come on the table and as side dishes just fresh salad of tomatoes, lettuce or carrots and a good bottle of Malbec. What more do you need? Something that might be worth mentioning is the cooking level. The Argentineans tend to like the meat more well done. Therefore you should order your piece “jugoso” (medium/rate). Try also blood sausage (morcilla) or a piece other than the fillet, you will love it.
Well, officially you can reserve tables at Don Julio, but it is always booked out. You better try it at noon or in the evening rather early or very late after 11pm. Even if there are many tourists at this wonderful place it is worth a visit.
