ABC News' Andrea Smith reports:

What to do if you're a New Yorker, running to catch your train, but really need to stop and pick up that last-minute gift? Make a stop at the new Apple Store at Grand Central Terminal, of course. Apple showed off what it says is one of its largest Apple stores yet - 23,000 square feet overlooking the historic main concourse of the terminal.

Apple's Bob Bridger said they'll offer everything customers are used to: Apple's Genius Bar for tech support, personal training, and a few new things designed for people who move at New York speed.

"We have all of our workshops as well as one-to-one training," he said. "We'll also have, exclusive to this store, 15-minute express workshops that are streamlined versions of all our favorite workshops."

So no problem if you need to learn in a hurry. There's also room for "personal setup," so customers can hop on the train and start using their new product. And there's also personal pickup, for users of the Apple Store App.

"Our Apple Store App, that's you can use your iPhone to actually make purchases online with the application," said Bridger, "whether you're on a train, in a taxi, or walking to the store, so when you get to the Apple Store at Grand Central you can actually just stop by and pick up your product when you get there."

And if you just feel like browsing the store, Apple says it's hired over 300 people to staff the Grand Central location. There's self-checkout for those with the iOS app, or EasyPay, Apple's new self-checkout program.

"We do have the EasyPay devices that allow customers to really just swipe their card when they're working with one of our specialists, when they want to buy one of the Apple products to make the process even faster."

Bridger said the location is "perfect for the hundreds of thousands of people who pass through Grand Central Terminal."

Apple's Grand Central Terminal Store opens to the public Friday at 10 a.m.
