When the weather turns in Hanoi
Northern Vietnam has a grey drizzle season around February to April that never quite rains and never quite stops. The response is coffee: the Old Quarter holds hundreds of narrow upstairs cafes where nursing one drink for two hours is expected behaviour. The Ethnology and Fine Arts museums are indoors. Lotte Center's 65th-floor observation deck and Trang Tien Plaza cover the mall option.
Hanoi's museums, and which one to pick
The Museum of Ethnology out in Cau Giay is the one worth the taxi: fifty-four ethnic groups documented indoors, with full-scale stilt houses and a towering Bahnar communal roof rebuilt in the garden. Hoa Lo Prison, the Hanoi Hilton to American pilots, presents itself mainly as a French colonial jail. The Vietnam Military History Museum moved in late 2024 to a vast new building out on the Thang Long boulevard.
What to eat in Hanoi
Pho began in the north and is served here with a few plain herbs rather than the southern basket of sprouts and hoisin. Bun cha, grilled pork dropped into a bowl of dipping broth, is a lunch dish that vanishes by two. Egg coffee, yolk whipped with condensed milk, was invented at Cafe Giang in 1946 and is still poured there. Cha ca, turmeric fish with dill, has a street named after it.
What first-timers get wrong in Hanoi
Count the zeros, because a 500,000 note and a 50,000 note are similar in colour and the mistake is routine. Book Grab or Xanh SM rather than flagging cars, since unbranded taxis with rigged meters still work the Old Quarter. A friendly man offering to fix your shoe will take it and then set a price. Ha Long Bay is a long drive each way even on the expressway, leaving only a couple of hours afloat.
What things cost in Hanoi
A bowl of pho on a street corner is 40,000 to 60,000 dong, roughly double in a sit-down restaurant. A glass of bia hoi runs five to ten thousand. A Grab motorbike across the Old Quarter costs 20,000 to 40,000. The Temple of Literature charges 70,000 and Hoa Lo Prison a similar amount. Old Quarter guesthouse rooms start well under a million dong a night.
