Lunch in Paris can get very pricey, and I like to eat like the locals, so I always go for a good, less expensive place like Brasserie Balzar (no. 49, rue des Ecoles, 5e - try the poulet roti and tarte au citron), Cremerie Restaurant Polidor ( rue Monsieur le Prince, 6e - blanquette de veau is nice, and the lentil soup is the best), or Perraudin (no. 157, rue St. Jacques, 5e - try the kir Maison). And do yourself a favor: stop at Angelina (226, rue de Rivoli, 1er, just down from the Louvre) and order the chocolat a l'Africaine, which some say is the best in the world. Have a great trip!
