Sonic is preparing to introduce a new take on its once-forgotten fries. They have not updated their fries in over ten years, but they are taking them to the next level with these 'Groovy Fries'. Fans will be eager to dip these crinkle-cut, perfectly salted fries along with their 'Groovy Sauce, ' which is a creamy ranch combined with the mild spice of Sriracha and herbs.
