On the same day McDonald's said it would begin testing delivery in New York, an order placed for two cheeseburgers, two large fries and a vanilla shake took about a half hour to arrive at the Associated Press headquarters.

The bill came to $23.32, including tip, nearly double the cost if a reporter had walked around the corner to the nearest McDonald's to pick up the food.

The world's biggest burger chain said that it was starting the test and teaming up with Postmates, a service that is also working with Chipotle and Starbucks.

It's the latest sign that fast food chains are eager to figure out ways to feed customer demands for greater convenience.  Already, Burger King has offered delivery in select regions since 2012.

Others are experimenting with quicker takeout.  Taco Bell lets customers order and pay in advance on its mobile app, and Starbucks said it plans to offer mobile pay ahead later this year.
