I had the torta. It was ridiculously good and a large portion. It could easily be two meals. For $7, that's not bad. Highly recommended.
Not very clear vegetarian options, but they seem happy to substitute rice and beans for meat upon request.
I love the food here. Best kept secret in Northfield. That location has always been a hardship -- wish more people knew about it.
Authentic, made right before your eyes -- and oh so good. (Close to my office helps too!)
