Pupusería San Miguel is a family-owned Salvadoran food business serving Humboldt County's North Coast, specializing in hand-made pupusas with fillings like cheese, beans, and chicharrón alongside sides such as plantain empanadas, yuca fries, and tamales. Rather than a fixed storefront, it operates as a pop-up at rotating locations including Eureka's Madaket Plaza, local farmers markets, and area events.
