La Napolitaine, 27 rue de la Porte Morard (in the lower end of town, by the river Eure). As the name suggests, it's Italian, but the cuisine (pizza, pasta, escalope, ... ) may not be recognised on the other side of the Alps. However, the pizza are huge as are the salads. Contrary to many restaurants in Chartres, it stays open "late" (get in by half past ten). Moreover, it has plenty of room.
