The Obamas shut down R Street at Florida Avenue NW in D.C. last night for a four-and-a-half-hour celebration of senior adviser Valerie Jarrett’s birthday.

Jarrett turned 57 on Thursday.

The motorcade rolled from the White House to Dupont Circle just before 7 p.m. on Friday, with President Obama and Michelle Obama getting out at Restaurant Nora.

The restaurant, in an otherwise residential neighborhood, is the country’s first certified organic eatery and uses ecofriendly and biodegradable cleansers and decorations. Michelle Obama celebrated her birthday here in 2010.

The White House press pool was socked away at a nearby Italian restaurant for the first half of the dinner then stuck in the press vans for the last two hours. Heavy security surrounded Restaurant Nora as a handful of people stood in the rain to see the Obamas, who were never seen by the press.

The motorcade didn’t leave the restaurant until 11:39 p.m.
