Burger 21® rolled out several new and enhanced menu items in order to appeal to the changing taste preferences of its guests. In addition, the brand has added a smaller milkshake option to the menu and its 10 Certified Angus Beef® burger options will now be prepared in a third-pound size.

"Our customers' feedback is what drives our business forward and we think they will be just as thrilled as we are about these new additions to our menu."
