A restaurant chain is a set of related restaurants, typically with the same name in many different locations either under shared corporate ownership (e.g. In-N-Out Burgers in the US) or franchising agreements. Typically, the restaurants within a chain are built to a standard format and offer a standard menu. Fast food restaurants are the most common, but there are also upscale versions. Restaurants chains are often found near shopping malls and tourist areas.
