Inside Apple’s new Grand Central Terminal store by Philip Elmer-DeWitt @FortuneMagazine December 7, 2011, 4:06 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons 2 Genius Bars, 45 display tables, 3 walls of accessories, free Wi-Fi and no “public” toilets View from a Mac table. Photo: PED Apple is reported to have paid $5 million to Metrazur Restaurant to buy out the eight years remaining on its Grand Central Terminal lease. We suspect both sides of the deal got a bargain. Metrazur, judging from the reviews in Yelp before it closed, was famous for strange sauces and slow service. Apple AAPL , judging from a tour of the new retail store it has built on the terminal’s east and north balconies — in more than twice the space formerly occupied by Metrazur — is going to move a lot of product when the store opens Friday at 10 a.m.. (Free T-shirts for the first 4,000 customers.) Grand Central is the world’s largest train terminus (by number of platforms) and one of the busiest places in the city that never sleeps. Some 750,000 people pass through its marble halls every day, and traffic swells to more than 1 million per day during the holidays. According to the Grand Central Terminal website, 50% of its commuters’ household incomes are over $100,000, and 20% are over $200,000. Apple is cagey about the dimensions of the new store. Press accounts put it at 23,000 square feet, which would make it, by our count, Apple’s third largest. Bob Bridger, vice president of retail, real estate and development, would only say that it is “one of the biggest.” This we know for sure: The store has 2 Genius Bars with 12 stools each 45 display tables covered with Macs, iPads, iPhones and iPods 3 walls of accessories 315 full and part-time employees (bringing Apple’s NYC total to more than 4,000) lots of free Wi-Fi (reachable from the terminal’s main lobby) minimal signage (three glowing Apple logos) No public restrooms (a requirement, according to Apple PR, of the Metropolitan Transportation Authority, which owns the building) Apple called to apologize and correct their initial answer to the most pressing question: There are, repeat are, restrooms available in the store for customers. Phew. UPDATE: The restrooms in the store are not — repeat not — open to the public, according to a security guard assigned to protect them. They are, however, open to customers, a distinction with a difference in a place like Grand Central. Bridger meets the press.
