Most Subway shops are pretty accessible to the normal lunchtime crowd. But the new one being introduced to the workers at the new tower at Ground Zero in NYC, well, it's a little harder to access: it's in a shipping container being held up by a crane.
Yes, it's a full-blown Subway with a full menu and fresh baked bread every day. It's location allows workers on the skyscraper to eat without going all the way down to the ground, which saves precious time. As the building goes up, so will the Subway, jumping up floor to floor with its crane.
