LONDON — When Jamaican sprinter Usain Bolt won the men's 100-meter gold at the London Olympics, he told reporters he had eaten a McDonald's wrap earlier in the day. It was a publicity coup for the fast-food chain that built a temporary restaurant just for the Olympic Games.

The company says it is the biggest and busiest McDonald's in the world. The two-story restaurant inside the Olympic Park is around 300 meters from the Olympic Stadium and has been flooded with visitors to the Games.

With a capacity to seat about 1,500 people and hundreds of staff on hand, it is churning out its trademark fast food for the duration of the Games.

At the busiest times the staff serves 1,000 customers in just an hour. Before the end of the Games, McDonald's says it will have served around 50,000 Big Macs.
