Popusas de chicharon con queso (pork and cheese) are the best! Ohh and the salad they give you on the side is also some of the best I've had. All of the popusas are made to order so it might take bit eat a little snack if your really hungry. They're hand made. The best thing is that you can see them making them if you stand by the cash register.
They are always very nice it almost feels like your family here. Being Mexican we don't really make popusas so at first I didn't know what I was ordering they will definitely help you out.
Enjoy
