<p><br /> US President Barack Obama and Russian President Dmitry Medvedev have taken a break from bilateral meetings at the White House to travel outside Washington DC for a quick, informal lunch.<br /> </p><p><br /> Traveling by motorcade, the two leaders headed for Ray's Hell Burger in Arlington, Virginia, a popular spot where Obama ate last year with Vice President Joe Biden.<br /> </p><p><br /> A cheer went up from customers when the presidents walked in, but the lunch crowd largely left the presidents alone. During their meal, Obama and Medvedev sat at a table with their interpreters, sharing a conversation through them.<br /> </p><p><br /> The US president had a cheeseburger with cheddar cheese, onion, lettuce, tomato and pickles, whilst his Russian guest had a cheeseburger with cheddar, onion, jalapenos and mushrooms.<br /> </p><p><br /> Obama drank iced tea and Medvedev sipped a Coke, while the presidents, both in shirt sleeves on a hot summer day, shared a portion of fries.<br /> </p><p><br /> Later in the day, and back to official business, the two leaders held a joint news conference at the East Room in the White House.<br /> </p><p><br /> Obama declared that he and Medvedev had "succeeded in resetting" the relationship between the former Cold War adversaries that had dipped to dangerously low levels in recent years.<br /> </p><p><br /> He directly acknowledged differences in some areas, such as Moscow's tensions with neighbouring Georgia, but said "we addressed those differences candidly."<br /> </p><p><br /> Obama also announced that the US and Russia had agreed to expand cooperation on intelligence and the counterterror fight and worked on strengthening economic ties between the nations.<br /> </p><p><br /> The US leader gave Russia perhaps the biggest gift it could have wanted from the meetings: an unqualified, hearty plug for Moscow's ascension to the World Trade Organisation. Russia has long wanted membership but US support in the past has come with conditions.<br /> </p>
