GrubHub is a web app that allows a user to search for food delivery options from local restaurants. Users can search by type of food to discover convenient local bites. Their semi-open API can be used by providers to update restaurant information such as addresses, hours, and cuisine types. The API can also be used to retrieve menu information from a database of 10,000+ restaurants. Currently the API does not offer public documentation, but interested parties can request app approval by emailing email@example.com.
