In the fall, Fairey installed a version of his iconic "Obama/HOPE" painting on the outside wall of the restaurant on the U Street corridor, named in honor of D.C. native and soul legend Marvin Gaye.
Even local churches reportedly are trying to woo the first family, which has not settled on a place to worship yet. On the Sunday before the inauguration, the Obamas attended services at the Nineteenth Street Baptist Church, one of the city's oldest historically black churches.
On Inauguration Day they stuck with tradition and attended services at St. John's Church across Lafayette Park from White House. Dubbed the "church of presidents," this is where the Bushes occasionally attended services when they were in Washington on the weekends.
Could the Obamas spark a surge in interest at local eateries and tourist sites, similar to the "Oprah effect"?
Washington tourism officials certainly hope so and liken it to the lure of celebrity sightings in Hollywood.
"The possibility of spotting the Obama family out and about can only add to D.C.'s appeal as a tourism destination," said Hanbury of Destination DC.
As they settle into their new home and city there is no shortage of suggestions for where the Obamas should go next. Local newspapers and blogs have come up with lists of must-see restaurants and cultural sites. Local sports fans are hoping that Obama shows up to a game to root on the home team -- as long as they are not playing a team from Chicago.
Perhaps a Georgetown men's basketball game is on the president's future schedule? Hoyas' head coach John Thompson III is a Princeton grad, like Michelle and her brother Craig Robinson.
At Ben's Chili Bowl, Obama was asked the key question: Georgetown or Maryland hoops? He demurred, saying on that issue he's neutral.
The Obamas remained inside the White House on their first weekend in their new home, no doubt disappointing restaurant and shop owners who were hoping for a surprise visit.
"I think it's great. It's hard to say how long that will continue. When President Clinton was sworn in the first time, he made a big show of going to Georgia Avenue and then wasn't as involved in the city after that. If you talk to people living here then, they were ultimately disappointed," DCist's Mathis said. "There is good reason to hope that the Obamas will continue to be visible."
"They said they will bridge the gap between the city and people who live here and more formal Washington. There's good reason to think that they might."
