Don't let the location fool you: This is the best place for a variety of latin american food from Ecuador, Chile, El Salvador, Peru, and Mexico to name a few.
Specifically I always visit the Ecuadoran restaurant because they are always open the latest and have to a variety of stuff to offer:
Humitas are made of corn and have cheese in the centre, I would get these if the Tamale de Pollo (chicken tamale with a burst of flavours) wasn't availible.
Can't forget the Empanadas de Queso (Cheese Empanadas) these are probably the best for munchies and you need to try them with suger on top or split it open and lightly sprinkle some inside (that's how some people from Ecuador really enjoy it).
Not only that, but they offer various soups and dishes, and you can get the typical dish served with either chicken, fish fillet (which is the best by far) or meat with rice, beans and salad. That is a typical dish as Arroz con Minestra (rice with beans).
