yeah, denny's must of been jealous of kfc and their double down sandwich, because they're rolling out something as heart attackingly "delicious." it's called the fried cheese melt.
so, you've got 4 mozzarella sticks inside of a grilled cheese sandwich. yep, sounds about right.
i can't get too high and mighty on this, because i've got to admit that i have eaten a similar hamburger at red robin that had mozzarella sticks on it (it wasn't very good).
