While there, it's worth splurging on one of DC's most sophisticated Sunday brunches in the Lafayette Room at the Hay-Adams hotel.
Just steps from the White House (and briefly home to President Obama in the weeks before taking office), this historic landmark oozes power and elegance. And serves an equally refined Sunday brunch buffet.
On three special occasion during the year - Easter, Mother's Day and Christmas Day - brunch takes place on the recently renovated hotel rooftop. The views are breathtaking and some of the best anywhere in DC, so plan ahead and bring a camera.
Of course, save room for dessert. Much of it is petitely portioned, so sample away. The pistachio creme brulee was a beautiful twist on a classic. The chocolate mousse martini was as fun to eat as it was to look at. Follow it all with a long afternoon stroll along the National Mall.
