Beer, known as the signature drink of Oktoberfest, just got a sweet twist. Now through November 11, Red Robin restaurants are serving the Samuel Adams Oktoberfest Milkshake.

Made with Sameul Adams Oktoberfest draft, vanilla soft serve and caramel, the adults-only drink is a fun take on your average brew.

"Now, our guests don't have to choose between a beer or a shake to go with their burger. They can have the very best of both in our new Oktoberfest Milkshake," said Red Robin's master mixologist Donna Ruch in a statement.

The restaurant is also offering a variety of other festive foods, like cheesy pretzel bites with beer mustard.

The Oktoberfest burger made a reappearance this year, complete with a "toasted pretzel bun slathered with beer mustard, topped with a fire-grilled beef patty, melted Swiss cheese, beer mustard sautéed onions, Black Forest ham and green leaf lettuce."
