A fast food industry magazine gives top marks to Chick-fil-A and Wendy's for drive-thru service.

QSR released its study this week, which rated speed and accuracy at six major fast food chains.

Chick-fil-A earned top honors for getting orders right 92 percent of the time. It also scored the highest for customer service and cleanliness.

When it came to speed, Wendy's had everyone beat. The burger chain completed drive-thru orders in about two minutes and ten seconds.

Taco Bell, coming in number two, was only 20 seconds behind Wendy's.

According to QSR, Burger King scored the lowest in both the accuracy and speed categories. The restaurant got orders right 83 percent of the time and took over three-and-a-half minutes to complete them.

McDonald's and Krystal finished in the middle of the group for most categories.
