McDonald's customers were not intrigued, but some international McDonald's still sell this item.
McDonald's Hula Burger
The Hula burger was McDonald's failed option for Catholics who coudn't eat meat on Fridays during Lent. The sandwich combined pineaple and melted cheese. If people weren't going to eat meat, it was clear that they would rather have a Filet-O-Fish than a pineapple and cheese sandwich.
McDonald's tried to entice customers with styrofoam packaging that separated the lettuce and tomato from the burger for maximum freshness. It didn't work, particularly since environmental advocates attacked the packaging.
Burger King tried to compete with White Castle sliders on numerous occasions. The burger chain offered Burger Bundles in the late '80s, Burger Buddies shortly after, as well as Burger Shots in the late 2000s. Changing the name didn't help; Burger King's customers did not seem to want to purchase these tiny sliders.
Taco Bell's Bell Beefer
Even though Taco Bell's slogan is "think outside the bun," the taco chain made a taco burger, bun and all. Customers were not intrigued by the ground-beef taco burger, and decided to stick to tacos at Taco Bell and burgers at other establishments. However, some customers miss the retired item; a small but loyal Facebook group, "Taco Bell Please Bring Back The Bell Beefer," begs the taco chain to revive the product.
These cheesy fries asked customers to do a little work: shake up fries in a bag with powdered cheese. In theory, it sounds like it could work, but this product didn't stay on the market very long.
The McAfrika — a pita with beef, cheese, lettuce, and tomato — was an enormous PR disaster. The sandwich was released in Norway during a famine in southern Africa. Unsurprisingly, McDonald's pulled the sandwich.
In summer 2013, Canadian McDonalds chains released the limited-edition McLobster, which promised "100% fresh Atlantic lobster," for a curiously low price below $7. Unsurprisingly, stomachs were turned and reactions were strong.
Wendy's attempt at a salad bar offered an all-you-can-eat buffet addition with hot food to the chain restaurant, but it was unsuccessful, and Wendy's nixed it.
McDonald's tried to appeal to gourmand grownups with this quarter pound burger. The "secret sauce" on the burger didn't help; after a huge marketing campaign, it wound up being one of the most expensive failures in McDonald's history.
McDonald's Salad Shakers
This healthy option didn't last too long, even if some people were fans of the shakable salads. But that was the problem — not enough people wanted to purchase it. Proof: a Facebook page called "Bring Back The McDonald's Salad Shakers" exists, but has less than 500 members.
McDonald's Onion Nuggets
In the 1970s, McDonald's introduced this fried snack that substituted chicken for chopped onions. It didn't last very long.
McDonald's Chicken Fajitas & Breakfast Burritos
McDonald's attempted to do Mexican food in the early '90s with chicken fajitas and breakfast burritos. Much like its other attempts at new cuisines, it did not go over particularly well. The item was discontinued.
The burger chain added this addition to the menu in an attempt to compete with Burger King's staple, the Whopper. The sandwich couldn't prove to be popular with customers over time, and it was pulled from the menu in 2010.
Pizza Hut's Priazzo
This mega-pizza with two layers of crust, ample cheese, and a ton of meat, was intended to imitate Chicago deep-dish pizza. Customers didn't appreciate how long it took to prepare the pizza, and given the enormous advertising campaign leading up to its release, the Priazzo was a failure.
