First tip: When travelling to Argentina, bring dollars or euros.

I normally don’t dine out but Argentina is the home of good meat and the best restaurants in Latin America are in Buenos Aires so yes, I did a lot of dining out in this country! You can check this list for reference: 50 Best Restaurants in Latin America
If you’re the travelling chef type, Supermarkets are for you. I find these prices really expensive (for what it looks like and quality-wise) but I am happy that I can drink the best wine here for a very cheap price!
Note that the above table is a price list for the capital, Buenos Aires. It may vary depending on the city you are in. For example, the South of Argentina can be really expensive because of its touristic reputation.
