All pavilions are matching the planets in the solar system. Each pavilion have its purpose: research library, museum, a repository for the collection of asteroids and meteorites, cafes, educational classes and more.
Neptune is molecular café. All planetarium visitors and citizens can visit it. I choose molecular cafe because of gastronomy and science combination.
Science library with book collection is planned in Saturn pavilion. The rings of Saturn is external Console, where you can sit, drink coffee and read a book.
