"High-End Vietnamese in Tranquil Location Inspired by the cooking of his wife's grandmother, Madame Hien is chef Didier Corlou's attempt at upscale but unfussy Vietnamese cuisine. Set in the former Spanish embassy, it is a beautiful spot for both lunch and dinner, with the outside courtyard in particular providing refuge from Hanoi 's busy streets. Dishes, meanwhile, run the gamut from traditional classics to Corlou's "New Hanoi" creations, adding exotic twists to familiar French and Vietnamese staples."
