I bought one for $1.
They're not kidding when they call this the "Fry Lover's." Compared to Burger King's French Fry Burger last year, this one has over twice the amount of fries. They were crispy and imparted a good amount of flavor with a mix of potato and spices.
Overall, Rally's Fry Lover's Burger was pretty enjoyable. The fries add quite a bit of flavor and texture and fits remarkably well with the standard plain hamburger.
