shop=Tortilleria ? Should it be shop=tortilla proposed at https://wiki.openstreetmap.org/wiki/Proposal:Shop%3Dtortilla ?

Is it amenity=fast_food or amenity=restaurant by any chance? Or are they selling pieces not ready to eat? Or ingredients? Maybe some https://wiki.openstreetmap.org/wiki/Key:cuisine would be a good idea?
