It was $4.99 for the burger (which is 40 cents more than a regular Whopper in my neck of the woods).
Unsurprisingly, the Four Cheese Whopper tastes like an extra cheesy classic Whopper. When I popped the hood, I didn't really see the three-cheese blend but it may have just melted into the melted American cheese slice and/or cheddar sauce.
The cheesiness is buoyed by the absence of tangy combination of mayo and ketchup that you find in a regular Whopper.
For a "fire-grilled" beef patty, it lacked any of the charred or smoky notes that usually accompany cooking over a fire. While thin, the patty filled the burger from edge to edge and delivered an enjoyable beef flavor.
