Red Robin says their $6.99 special on the Oktoberfest Burger ends Oct. 17, 2011.  The burger has been on special since Sept. 19 and ends on Monday, Oct. 17, 2011.   Normal price for the gourmet burgers is about $9.

The burger (with unlimited fries) is a fire-grilled beef patty, melted Swiss cheese, beer-mustard sautéed onions, Black Forest ham and green leaf lettuce.

“The upcoming fall season was the inspiration behind this burger because the flavors are reminiscent of fall days and tailgating – grilling at a football game, eating hot pretzels with mustard, and enjoying a beer,” said Red Robin executive chef Dave Woolley. “I took those flavors and made that into a burger that would be a perfect option for our burger-loving guests.”

The Oktoberfest Bürger is available for $6.99 from Sept. 19 to  Oct. 17, 2011.
