Just a word of friendly advice: you may develop a craving for these empanadas, so try at your own risk! The beef empanadas are perfection, flavorful with a good portion for the price (although if you're not a fan of olives or raisins like myself, you can just pick them out), and the salsa, like others have stated, is divine. I would recommend the corn pie, but ideally it should be shared between 4-5 people, not just because of the size but because of its sweetness.
Only downside: very limited seating with tiny tables, so it's probably not a good idea to go during prime lunch or dinner time.
