Denny's launches beefy mac 'n cheese sandwich

Denny's - the US-based all-night casual dining chain that makes a sport of topping itself in extreme foods - is at it again with the launch of a grilled cheese sandwich stuffed with macaroni and cheese and a beef patty blanketed in Frisco sauce.

Their Mac ‘n Cheese Big Daddy Patty Melt is part of the diner's ‘Let's Get Cheesy' menu which launched this week across the chain's US locations and includes a hand-pressed beef patty topped with their new creamy white macaroni and cheese, melted cheddar cheese and a zesty Frisco sauce stuffed between two slices of grilled potato bread. Frisco sauce is a mix of salad dressings. The meal is served with wavy-cut fries.

The new menu also includes five other cheese lovers' dishes like a three-cheese omelette; fried beef steaks covered in a pepper jack cheese sauce; and a breakfast sampler with cheddar smoked sausages and scrambled eggs with cheese and hash browns.

Dessert offerings include Strawberry Pancake Puppies with a cream cheese icing and a Strawberry Cheesecake milk shake.

To promote the limited-time menu, Denny's has also launched a "Cheesiest Joke" competition on Twitter, inviting its 10,250 followers to submit their ‘cheesiest' chat-up lines and jokes.

Earlier this year, the all-American diner served a Baconalia menu that included a maple bacon sundae: vanilla ice cream topped with maple flavored syrup and hickory-smoked bacon.

In July, Denny's was singled out along with casual restaurant chains like The Cheesecake Factory and Applebee's for serving some of the most calorific meals in the US. In spite of items like deep-fried mozzarella sticks stuffed in a grilled cheese sandwich, Denny's also offers a lighter menu of salads, while The Cheesecake Factory launched a new low-calorie menu weeks following the damning report. Applebee's also offers a menu with items under 550 calories.

Denny's has 1,500 locations in the US, Canada, Costa Rica, Guam, Mexico, New Zealand, Puerto Rico and Japan.
