Chick-Fil-A has plans on bringing another milkshake flavor to their menu. From now until April 24th the restaurant chain will be testing out a Butterscotch Crumble Milkshake at select restaurants in Salt Lake City, Utah. According to Chick-Fil-A, the milkshake is a perfect match for the waffle fries because of the sweet and salty flavors. If you are wondering why Salt Lake City was chosen as the test city, well it's because the residents ordered over 1.5 million milkshakes just last year.
