Who's really the fastest among the fast food giants?
A new study gives Chick-fil-a and Wendy's top marks for drive-thru service.
Chick-fil-a was number one by getting 92% of the orders right.
They also get the top score for customer service and cleanliness.
But Wendy's was by far the fastest.
Averaging two minutes, 10 seconds per order.
That's 20 seconds faster than Taco Bell, which was 2nd.
Burger King came in last for accuracy and speed.
While McDonalds finished in the middle.
