OpenTable, the online restaurant booking service, announced yesterday that it will give restaurants a free mobilie version of their site--if they sign up before February 2013.

The San Francisco-based company is extending the offer to all eateries in the U.S., Canada, and the UK, as long as they don't drop the OpenTable service immediately afterwards. OpenTable will partner with mobile website developer DudaMobile, a start-up that raised $6 million in series B funding earlier this year, according to TechCrunch

Turns out, only 10% of restaurants have "mobile friendly websites"-- a percentage that needs to increase to keep up with the consumer shift towards mobile. 

As for OpenTable, according to the outlet, an increasing amount of diners book reservations on OpenTable via a restaurant’s mobile site, so the move is somewhat natural. In Q2 of 2012 alone, OpenTable said it assisted more than 30 million online reservations through mobile devices, which was more than $1 billion in revenue for the restaurateurs partnered with OpenTable. 

"By removing the added time and cost required to create and host mobile-friendly sites, we are making it simple for restaurants to reap the benefits of the shift to mobile," Mike Xenakis, Managing Director of OpenTable Europe, said in a statement.  Should a restaurant sign up the website streamlining service after February 2013, they will have to pay a monthly fee of $100.
