There's a new top burger in America.

FOX's Lilian Woo reports:

The favorite burger chain in the country comes from Five Guys, according to a study out this week, which says it displaced In-N-Out Burger, which fell to second place.

In the Harris Poll's annual Equitrend study, Shake Shack came in third place. All three chains turn out relatively thin seared patties made from fresh ground beef on soft style buns.

Separately, Starbucks rose in the rankings, beating out Dunkin' Donuts this year. A vice president at the Harris Polls says restaurants continue to adapt to the millennial lifestyle and improvements in ordering methods such as Starbucks' mobile app are likely influencing ratings by millennials.
