KC Juice dethrones Smoothie King

There is no smoothie crown in Kansas City, but there is a king. Smoothie King (8825 State Line Road) and KC Juice (4141 Pennsylvania) are two of the most well-known fruit-slinging operations in the city. Smoothie King has more than 600 locations, including a second in the works in Kansas City. KC Juice is a stand-alone operation in Westport.
So is it the well-tested franchise or the social-media-savvy juice bar that deserves the crown? Let the battle of whirring blenders and crushed fruit commence.
