Inside Obama's favourite burger joint
Until Barack Obama was elected US president, Ray's Hell Burger in Arlington, Virginia, was just an out-of-the-way fast food joint.
But things first started to change when he took his Vice-President Joe Biden there for a bite to eat.
The next thing owner Michael Landrum knew, he was hosting a lunch meeting between Mr Obama and Russia's Dmitry Medvedev - where both ate cheeseburgers.
So how has life changed for Ray's Hell Burger since it became the haunt of world leaders?
BBC News went along to meet Michael Landrum and get a tour of his restaurant.
