Is this a street food (as in, not only in rettnuraass)? If so, how is it served?Yes, especially at the beaches in Ecuador you will find ceviche carts everywhere. The ceviche is usually served in plastic bowls or cups, topped with maiz tostado (a type of South American corn nut), chifles or green plantain chips, or patacones (thick plantain chips). You can also ask for them to add some aji or hot sauce to your ceviche.
