It was named the burger of the year by Time magazine.
Now the Pretzel Bacon Cheeseburger may be on its way to New Zealand.
The Wendy's burger with pretzels in place of traditional buns was named 2013's "most important" and "most talked about" fast food snack.
Time magazine cited a Burger Business report saying no other burger was anticipated or more scrutinised.
"Its popularity cemented 2013 as the Year of the Bun," it said.
