Ericilia's may not have much more ambience than a fast-food restaurant. After all, the bathroom is a locked vault with security that rivals Fort Knox. But the food is muy excellente and the prices would be unbelievably cheap even in a town where bargains are everywhere - much less the somewhat pricey environs of DC. You won't hear much English spoken here -- the patrons are heavily Salvadoran -- and you might catch some Spanish-language football (that's soccer to Americans) on the TV. I only tried a tiny sampling of the very extensive menu - pupusas - but they were outstanding.
