I don't know why this place has such great reviews. We ate there last night for the first ( and possibly the last) time and it was underwhelming and greasy. It could have been a bad day - they were really crowded because of the winter solstice celebrations but I don't know if I want to go back and verify this.
It was super cheap though.
We had the vegetarian empanadas. There was a minuscule bowl of salsa accompanying it.
We've had much better luck with other South American restaurants in the area.
