A butler café is a subcategory of cosplay restaurant that originated in Japan. In these cafés, waiters dress as butlers and serve patrons in the manner of domestic servants attending to aristocracy. Butler cafés proliferated in reaction to the popularity of maid cafés and serve as an alternative category of cosplay restaurant intended to appeal to female otaku.

A theme restaurant is a type of restaurant that uses theming to attract diners by creating a memorable experience. Theme restaurants have a unifying or dominant subject or concept, and utilize architecture, decor, special effects, and other techniques, often to create exotic environments that are not normally associated with dining because they are inaccessible, no longer exist, are fictional or supernatural, or taboo. The theme may be further extended through the naming and choices of food, though food is usually secondary to entertaining guests.
