All-day McDonald's breakfast is missing some popular menu items

Fans of McDonald's have begged the chain for years to serve its breakfast menu past 10:30 a.m.

McDonald's will finally answer their prayers Tuesday with the rollout of an all-day breakfast menu.

But there's a huge catch.

The all-day menu will be limited to only a couple breakfast sandwiches, pancakes, and sides.

Hash browns, a McDonald's breakfast staple, won't be available at all restaurants because they are made with the same fryers as the french fries. McGriddles and bagels also won't be served.

For the all-day menu, McDonald's restaurants will serve either McMuffin or biscuit sandwiches - not both - depending on local preferences, according to the company.

The restaurants serving McMuffin sandwiches will serve only three kinds: egg, sausage with egg, and sausage.

Those serving biscuit sandwiches will also have three options: bacon, egg, and cheese; sausage with egg; and sausage.

Pancakes, sausage burritos, yogurt, and oatmeal will also be on the menu.

McDonald's is limiting the menu to prevent kitchens from getting overwhelmed by cooking breakfast and burgers at the same time.

The chain has previously said it doesn't serve 24-hour breakfast because its grills aren't big enough to handle breakfast and lunch items.

"It comes down to the sheer size of kitchen grills," the company said on its website. "They simply don't have the room for all of our menu options at one time - especially considering we use our grill to prepare many items on our breakfast menu."

Franchisees are adding equipment like extra grills and toasters to accommodate the new breakfast hours.
