A food theme park, also called a food museum, is generally a single place with many food shops selling the same kind of food, or a food 'theme'. A food theme park, unlike a conventional theme park, is located indoors. Food theme parks are mostly located in Japan where they are called by the English locution (フードテーマパーク (Fūdotēmapāku)).
