We taste-tested hot dogs from all of the major fast-food burger joints - and the winner was surprising

The fast-food hot dog wars are on.

On February 23, Burger King added grilled hot dogs to the menu.

Checkers & Rally's responded the next day by selling its hot dogs for 79 cents.

"It's a war we plan to win!" the company said in a news release.

But who serves the best wiener?

I taste-tested hot dogs from Five Guys, Burger King, Shake Shack, and Checkers. The winner surprised me.
