Well according to sources the construction may start from next week in the Grand Central Station, New York. This location is quite big and will also make a quie big Apple Retail Store in future.
The New York Times reports,
When Apple proposed opening a store on the balcony overlooking the main hall, it submitted its bid in linen-lined boxes, as if it were a wedding present to transit officials, a source familiar with the application process said. The board is expected to approve the deal as early as next week, at its monthly board meeting.
This Apple store is just not big it will be a grand store plus the worlds largest Apple Retail store and will be named ‘Apple Store, Grand Central‘. In this store 700,000 people/customers will be easily spaced to move around.
