Updated November 7, 2026. Read from All the Places. All the Places data is CC0-1.0, a public domain dedication. Each location is read from the brand's own store locator by the All the Places project, which runs about once a week, so a location can have opened or closed since the run date. A brand is keyed on its Wikidata item when the project gives one, else on the project's own name for that brand's locator; two brands are never merged on a name. A repeated address of one brand counts once. Locations named for a private person are left out. Opening hours are shown as the brand lists them.
