The United States has only a handful of permanent maid cafes, and most of them are in Greater Los Angeles: the San Gabriel Valley (Monterey Park, Arcadia) and north Orange County. Akihabara-style service, live shows and cheki photos.
MaidLink lists 3 permanent maid cafes in Los Angeles. Pop-ups and convention events are not included.
It depends on the cafe — some take walk-ins, others sell timed tables. Check the official links on each cafe's page.
These cafes follow the Akihabara format — the greeting, drawn latte art, live songs and cheki photos — with local prices and menus.
