It's a small town, after all. On Sunday, as the Obama motorcade was barreling down Massachusetts Avenue, coming from daughter Sasha's basketball game in Chevy Chase, Md., the White House pool reporter noted that they passed by Bill and Hillary Clinton, out walking their dog.

On Saturday night, a tuxedo-clad former Senate Majority Leader Bill Frist, R-Tenn., was spotted with a female companion ducking into the downtown restaurant Lincoln for some late-night champagne and deviled eggs. The two stayed there until about 1 a.m.

And then on Thursday night, a restaurant rep tells us that three members of the Robert Mondavi family were having dinner at Bibiana. Michael, the California vineyard operator's son, and his wife, Isabel and their daughter, Dina were all at the downtown eatery.
