So much for America's birthday, now it's time to celebrate France's. Bastille Day is this Monday, and Dominique's restaurant holds its annual Bastille Day Race. At 2:30, at the pop of champagne cork, waiters and wairtresses will be racing from the restaurant at 20th and Pennsylvania to the White House and back, balancing a split of champagne and two glasses on a tray. (Waiters, waitresses and chefs: To enter, call 452-1126.) In Annapolis, the day begins with a sidewalk cafe at 11; crepes, French cheeses, wines and fruits. Events include French music and dancing, and Parisian fashions from 11:30 to 3; there's even a casino, Monte Carlo style, from 8 to midnight, all at Maryland Inn at the Church Circle in Annapolis. fFor dinner reservations or information, call 261-2206 in Washington, or 301/263-2641 (Annapolis) or 301/269-0990 (Baltimore).
