Restaurant reservation provider OpenTable has now seated over a million diners through its mobile apps for the iPhone, Palm, Blackberry and Android operating systems. Based on a $50 average check per diner that translates into more than $50 million in revenue for OpenTable's restaurant partners, according to the company.

Because our mobile apps interact directly with the OpenTable Electronic Reservation Book at the restaurant's host stand, we are uniquely positioned to provide smartphone users with the ability to find and book real-time reservations and the confidence that the restaurant will be expecting them when they arrive,"according to OpenTable CEO Jeff Jordan

OpenTable allows diners to find and book reservations at more than 11,000 different restaurants in multiple countries from the Web or a smartphone. By using any of OpenTable's mobile applications, diners can view a list of available tables at nearby restaurants and make reservations from their phones.

While OpenTable applications are available only for the iPhone, Palm, Blackberry and Android platforms, users of other types of smartphone can book reservations through OpenTable by pointing their browsers to its mobile-optimized Web site at mobile.opentable.com.
