Maid cafés are a subcategory of cosplay restaurants found predominantly in Japan and Taiwan. In these cafés, waitresses, dressed in maid costumes, act as servants, and treat customers as masters as if they were in a private home, rather than as café patrons. The first permanent maid café, Cure Maid Café, was established in Akihabara, Tokyo, Japan, in March 2001, but maid cafés are becoming increasingly popular. The increased competition drove the cafes to employ more diversified themes, gimmicks and even unusual tactics to attract customers. They have also expanded overseas to several countries around the world.

Cosplay restaurants are theme restaurants and pubs that originated in Akihabara, Tokyo, Japan, around the late 1990s and early 2000s. They include maid cafés and butler cafés , where the service staff dress as elegant maids, or as butlers. The staff treat the customers as masters and mistresses in a private home rather than merely as café customers. Such restaurants and cafés have quickly become a staple of Japanese otaku culture.
