Hanoi, the artistic and intellectual capital of Vietnam, is famous for local delicacies like Cha Ca La Vong (grilled fish seasoned with garlic, ginger, turmeric and dill), Pho Cuon (a special food made by packaging fried beef with onion, lettuce, cucumber in one neat little parcel), Ca Phe Trung (Vietnamese “egg coffee”), etc which are served in both street vendors and in luxurious restaurants.
