"Restaurant to Another World" is a fantasy slice-of-life anime centered around a mysterious restaurant called "Nekoya," which serves as a bridge between the human world and a fantastical realm. The restaurant operates every Saturday, offering a unique dining experience to a diverse clientele that includes humans, demons, elves, dragons, and other mythical beings. The establishment is run by a skilled and enigmatic chef known only as the Master, who prepares a variety of Japanese and Western dishes with meticulous care.

The narrative unfolds through episodic vignettes, each focusing on different patrons who visit Nekoya. These characters come from various backgrounds and cultures within the fantasy world, each with their own reasons for seeking out the restaurant. The dishes served, such as curry rice, hamburgers, and parfaits, often evoke strong emotional reactions, becoming a source of comfort, nostalgia, or discovery for the patrons. The interactions between the Master, his assistant Aletta—a demon girl who becomes a waitress—and the customers highlight themes of cultural exchange, hospitality, and the universal joy of food.

Key recurring characters include Aletta, who initially stumbles into the restaurant as a starving refugee and later becomes an integral part of its operations. Other notable patrons include the dragon princess, who develops a fondness for pudding, and the elf warrior, who finds solace in the restaurant’s peaceful atmosphere.
