OpenTable is an online restaurant-reservation service company founded by Sid Gorham, Eric Moe and Chuck Templeton on 2 July 1998 and is based in San Francisco, California. In 1998, operations began with a limited selection of restaurants in San Francisco. Restaurants used the company's back-end software to process the reservations made on the website, resulting in a real-time reservation system for both diners and restaurants. The service has since expanded to cover more than 50,000 restaurants in more than 80 countries.
