7 Secret Fast-Food Menu Items You Should Try Right Now

Fast food chains often feature secret menu items that are not listed on standard boards but can be ordered by customers who know how to ask. These hidden options range from customized sandwiches to unique dessert combinations, offering alternatives to regular menu selections. While these items are not officially advertised, they have gained popularity through word-of-mouth and social media sharing.

In-N-Out Grilled Cheese

In-N-Out Burger offers a grilled cheese sandwich on its not-so-secret menu, which the chain has published online. This item consists of melted cheese between two buns and is designed for customers who prefer not to eat meat. Another well-known option is ordering food “Animal Style,” which includes a mustard-cooked beef patty, pickle, extra spread and grilled onions.

Arby’s Meat Mountain

Arby’s Meat Mountain is a secret menu sandwich that combines multiple meats, including chicken tenders, roast beef, turkey, ham, pastrami, brisket, bacon, and fish, depending on location. It is topped with cheeses such as Swiss and cheddar. According to a former employee quoted in the source, only the roast beef and chicken come warm by default, so customers may request that all meats be heated before assembly.

McDonald’s Apple McFlurry

McDonald’s customers have created the Apple Pie McFlurry by blending a baked apple pie into a vanilla McFlurry. This dessert is not on the official menu but can be prepared if the restaurant’s McFlurry machine is operational. The treat combines the warm, spiced filling of the apple pie with the cold, creamy texture of the McFlurry.

Shake Shack Beer Float

At Shake Shack, some customers order a Beer Float, which involves adding a scoop of the chain’s frozen custard to a glass of beer. What we have is distinct from a root beer float and makes use of the restaurant’s offering of alcoholic beverages. The result is an adult-oriented beverage that mixes the sweetness of frozen custard with beer.

Raising Cane’s Double Butter Texas Toast

Raising Cane’s allows customers to order Texas Toast with butter applied to both sides, a variation sometimes referred to as the “Texas Toast B.O.B.” (Butter on Both Sides). One customer quoted in the source noted that this preparation method has been popular for about a decade, stating, “We’ve been toast Bobbing for about 10 years now. Only way to go.”

Subway Old Cut

Subway customers can request their sandwiches be made using the “Old Cut” style, also known as the V cut, where the bread is hollowed out rather than sliced down the middle. This method allows for more meat to be placed inside the sub. One former manager shared that this cutting technique was used in the 1980s and was considered safe and effective when meats and vegetables were prepared in-house.

Five Guys Patty Melt

Five Guys offers a Patty Melt sandwich, which began as a customer-created menu hack but was later added to the official menu due to its popularity. The sandwich is described as a vegetarian option by the source, though it typically includes a burger patty, melted cheese, and grilled onions on rye bread. Five Guys confirmed the item’s official status, stating, “We saw how much our fans loved the menu hack Patty Melt, so we decided to make it an official menu item! It’s available everywhere, so grab yours today!”
