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.

Akihabara is a neighborhood in the Chiyoda ward of Tokyo, Japan, generally considered to be the area surrounding Akihabara Station. Administratively, the area named Akihabara is actually found in the Sotokanda (外神田) and Kanda-Sakumachō districts in Chiyoda. There also exists an administrative district called Akihabara in the Taitō ward further north of Akihabara Station, but it is not the place people generally refer to as Akihabara.
