Those on the west coast might find trouble with the fact that their beloved burger chain, In-N-Out, was beat out by Five Guys for America's favorite in The Harris Poll's annual EquiTrend Study. This is the first time Five Guys has been crowned the burger champion, dethroning In-N-Out, which has held the top spot for the last two years.

Some Atascadero diners were surprised to learn about the shift, but Five Guys supporters in Arroyo Grande thought the switch was well deserved.

The Harris Poll reached its result after surveying more than 10,000 people aged 15 and above, and Five Guys emerged as the clear victor in this category.

The Harris study, in its 29th year, measures the strength of brands across various media - from travel to finance to restaurants.

The success of Five Guys in the survey has partly been put down to its rapid growth over the last few years, to the point that there are now well over 1000 branches in the U.S. and many more overseas.

Though McDonald's earned the top ranking for familiarity, overall, the world's largest fast food chain by revenue ranked seventh, behind Shake Shack, Wendy's and even Whataburger. After McDonald's it was No. 8 Sonic, 9.

Failing to make the list: Burger King, Jack in The Box, Carl's Jr., Checkers/Rally's, DQ Grill & Chill, Hardee's, Jack in the Box and White Castle.

The results mean that the only burger in the poll's top three which remains elusive to Londoners is In-N-Out. It expanded out of the Northern Virginia area in 2003 and has grown to 1,500 locations throughout the United States. The chain is popular for its simple and tasty burgers available with a slew of toppings to suit every taste and preference. In 2013 only 48% of respondents were familiar with Five Guys, according to the Harris Poll. That figure is now 68 percent, with Five Guys reaching 81 percent familiarity among Generation Z and millennials.

Other favorite restaurants included: Casual Dining (Cheesecake Factory), Chicken (Chick-fil-A), Coffee (Starbucks), Mexican (Moe's), Ice Cream (Ben & Jerry's), Pizza (Papa John's) and Sandwiches (Subway).
