Casita Salvadorena is a great little place I found. I grew up in central america and one of the great foods to eat I miss is Salvadorian Pupusas. They are kind of like a corn tortilla stuffed with different things. This place has great pupusas. You should check it out.
Here is a link to a googlemaps of it.
There's another good place to get Papusas over in Irving. From 183 exit Story and go South. Les than a mile down the road on the left, just past the carniceria there's a Salvadorian place. The owner is always there, and one of the few people who speaks English in the place.
The Salvadorian plate comes with 2 papusas, a tamale, plantain and beans. Incredible!
