A good place for El Salvadorean food, and more accessible to non-Salvadoreans than most, without selling out on the quality side. There is no doubt what you should order here: two mixed pupusas, one corn tamale, and perhaps a side order of beans. That makes for a great five dollar meal. Some of the other menu items are good here as well, but I am never really tempted to deviate from the above.
