On the recently released official 2013 Disney Deluxe Dining Plan guide (PDF), Disney have quietly added Epcots Le Cellier Steakhouse as a 'Signature' dining location for lunch. The restaurant became a signature location back in March 2011 for its dinner menu, however at the time its lunch service stayed as a standard single-credit menu.
The difference for guests is that with it now being a 'Signature' lunch, you will need to use two Disney Dining Plan credits instead of 1, and its menu quality will be increased. This will obviously also mean a higher pricing on items for guests not on the Disney Dining Plan.
Le Cellier is located in the Canada Pavilion of Epcot's World Showcase.
