Jack's Late Night Munchie Meals comes with two tacos, Halfsie fries (half French fries, half seasoned curly fries) and a 20-ounce stacked grilled cheeseburger. It's basically just a cheeseburger made with grilled cheese bread with a grilled cheese on top. According to the image on the website, it looks like it has some kind of white sauce like ranch or something like that, but I couldn't taste it. It basically knows exactly how you expect it.
It's like any other cheeseburger, but with an additional roll and cheese. The original variety of sandwiches are individual candies coated in milk chocolate with a center of caramel and cookies.
