I work down the street from this location and I'm glad I do! They have a good selection of pupusas and all of the ones I have tasted haven't let me down. My favorites are the chicharon and queso as well as the shrimp pupusa. They are served with some tasty black beans and some rice. Both of these are very different from what you get in a Mexican restaurant.
To drink I ordered horchata, which I guess in El Salvador is different from Mexico. It has a slightly nuttier flavor but it's still very good and refreshing.
Next time we go back, we will try one of their entrees (with a couple pupusas on the side) and see what else this Salvadorean cuisine has to offer! If it's anything like the pupusas, I am sure to be satisfied!
