No, the french fry burger will not blow your mind. It will bolster a languishing Burger King dollar menu. French fries on top of a burger? Who would come up with such simplistic brilliance? That's meant to be the point: simplistic brilliance, the type that kids can generate. The french fry burger, by falling onto the value menu, is not trying to do too much, but it is filling a gap.
Let's call this the: 'I just want a taste' gap. It's the refrain of weight-conscious wives around the world. You don't want the whole thing. You don't want to pay for it, you don't want to feel like you should eat it all, and you don't want the calories. You just want a taste. The fry burger is not exactly a sample cup, but it fills the same void. There's plenty of people who like fries, and can feel regret on the level of heartless betrayal when they walk away from a fast food restaurant without getting any fries. It's akin to getting a hotdog from the concessions at the movie theater. It's not bad, but it wasn't popcorn.
The fry burger gives you just a taste, a scattering of fries to go with the main item. And there's no fear of a taste clash. Burgers and fries go together like, well, like meat and potatoes. The question remains: how big of a 'just a taste' group is there to keep this afloat?
