Pretty much every restaurant in the Old Quarter stays open late. In fact, I would say that most of the restaurants I've been to in Hanoi take their final order at 10:00. Certainly all the Indian and pizza joints fit into this category. As do the bars (R&R, Le Pub, etc.). The restaurants behind the Sofitel do as well, and so do many of the restaurants near West Lake.
