The new two-storey structure will be built close to Apple's headquarters in Cupertino, California, after the project was recently approved by the local planning commission.
Alongside a place to eat, the restaurant will have an underground garage, lounge areas, courtyard and meeting rooms.
Apple is known for closely guarding secrets about its upcoming new products, often going to great lengths to keep out prying eyes and ears.
The company already runs a restaurant in Cupertino, called Caffe Mac, but it is open to people who do not work at Apple.
Only Apple staff will be able to visit the new restaurant, allowing them to freely discuss current or future projects without the fear of being overheard.
Dan Whisenhunt, Apple's director of real estate facilities, said: "We like to provide a level of security so that people and employees can feel comfortable talking about their business, their research and whatever project they're engineering without fear of competition sort of overhearing their conversations."
Entire websites are dedicated to rumours about new Apple products, meaning the US tech giant has to wage a constant battle to retain levels of secrecy.
In 2010, technology website Gizmodo famously secured a prototype model of the iPhone 4 ahead of its launch, after an Apple employee had left it in a bar.
Gizmodo eventually returned the prototype, but only after publishing photos and a video of the device on its website.
A prototype of the iPhone 4S is also thought to have been lost in 2011, although the handset has never been recovered.
Adam Lashinsky recently noted in his book Inside Apple that "company lore" suggests employees can be fired if they are found to have let out secrets.
The writer cited the example of someone losing their job after undercover Apple security officers at BJ's Restaurant & Brewhouse across Apple's main campus overheard them discussing sensitive information in public.
