WASHINGTON -- President Obama and Russian President Dmitry Medvedev have made a surprise visit to a popular hamburger spot just outside the U.S. capital.

Traveling by motorcade, the two presidents decided to go on a burger run for lunch. They ventured to Ray's Hell Burger -- the same restaurant where Obama once ventured with Vice President Joe Biden.

A cheer went up from customers when the presidents went in.

The lunch journey came after Obama and Medvedev held meetings at the White House.
