Justice Sandra Day O'Connor, chortling at the annual Hexagon satirical show, in Georgetown. The usual bevy of belles warbled, sporting judgely robes. Then they shucked them for the usual sequin-spangled, slightly clad kickline . . . Burt Reynolds and Goldie Hawn supping te te-a -te te at L'Auberge Chez Francois, before their flit back to glitter city. (Surely you spotted them in town to toil on their flick, "Best Friends"?) . . . A belle epoque aborning at Chez Camille. Big bucks are to be sunk into the midtown eaterie by Deepak Singh, an Indian-born entrepreneur who plans a pukka redo. (The munchies, naturellement, will remain the same. So will cute Camille) . . . Glossy little Dossier, the mag that tracks the Social Scene, laying out its wee welcome mat for the upcoming Moon-owned Washington Times: "The Moon Menace Comes to Town!" hollers a headline on a full-page editorial by Dossier president David Adler. (He was once Moonified himself, recall) . . . Smith Hempstone, Star-man of yore, hopping aboard said Washington Times as executive editor; Anne Crutcher, scribe of Food and Thought for three Washington papers, crowned its editorial page editor . . . Powder and Smoke--Georgetown shopping spot for fards and fragrances for the Divine--slamming its doors shut after 20 years of beautifying the likes of Liz Taylor and Nan Kissinger. (But you'll spot leftovers at Doc Dalinsky's Georgetown Pharmacy, snuggled next to Art Buchwald's stogies. Doc's mate Marian, you see, was the priestess of Powder. Now, she wants to put her feet up.) And the city throbs on.
