This is in fact northern Argentinean food, rural style. Excellent sausage, good empanadas. I liked the soup with chicken, corn, and dumplings. The humita (corn and cheese tamale) was very good too. They serve true Argentinean pizza, which gets good reviews but I haven’t tried. The way to go here is to treat it as a snack shop with some unique savory treats. I would resist the temptation to make it your main steak house. I don’t doubt the meat here is pretty good (and pretty expensive), but going the meat-only, large plate route to me seemed like it would be a bore, I don’t think I will ever try that. For taste and uniqueness I give this place high marks, use it properly and you should too. DC actually has a northern Argentinean restaurant, let’s be proud of that.
