The hoopla around Hanoi:
Although not the country‘s biggest city, Hanoi is Vietnam‘s capital and celebrated its 1,000-year anniversary in 2010. Hanoi can lay claim to being the first city in Vietnam with Western-style universities and is home to the Temple of Literature. Some other historically relevant sites of Hanoi are the Flag Tower of Hanoi and the Hanoi Cathedral. Also, it‘s said that Vietnam‘s most popular dish, Pho, originated in this city.
