Hanoi eats outdoors, on plastic stools, one dish per address. This three-day route works the wet markets and guild-street specialists of the Old Quarter, the turmeric-and-dill ritual of chả cá, and ends at the bia hơi junction on Tạ Hiện.
Hanoi's largest covered market, rebuilt in 1994 after a fire; wholesale trade starts before 05:00 and the food alley behind on Ngõ Đồng Xuân serves bún chả que tre, bánh tôm and chè. Open 06:00–18:00 daily.
The old wet market moved to Gia Ngư in 2010 but the roast-meat stalls stayed: lacquered suckling pig, roast quail, chả mực and braised pork sold by weight from 09:00 until they sell out, usually by mid-afternoon.
Birthplace of cà phê trứng in 1946, invented by Nguyễn Văn Giảng when fresh milk was scarce: egg yolk whipped with condensed milk and floated on dark Robusta. Down a corridor, upstairs, open 07:00–22:00.
The Trúc Bạch peninsula invented phở cuốn — sheets of fresh pho noodle rolled around stir-fried beef, lettuce and herbs instead of served in broth. Pair it with phở chiên phồng, puffed fried noodle pillows in beef gravy. Open 09:00–22:00.
Steamed rice crêpes spread by hand across cloth stretched over a boiling pot, filled with wood-ear mushroom and minced pork, then buried in fried shallots. Dipped in nước chấm scented with cà cuống. Open 06:00–22:00.
One dish only: turmeric- and galangal-marinated hemibagrus catfish finished at your table in a pan of dill and spring onion, then piled onto rice vermicelli with roasted peanuts, mắm tôm and herbs. Sittings run 10:00–21:30.
The plastic-stool crowd on the cathedral corner drinking trà chanh — iced green tea with lime and sugar — with bánh gối, nem chua rán and sunflower seeds. Stalls set up from mid-afternoon and stay busy until late evening.
A two-floor house serving northern-highland Thái dishes rarely on tourist menus: buffalo skin salad, grilled river fish, sticky rice steamed in bamboo and pork with mắc khén pepper. Floor mats upstairs; open 11:30–22:00.
Three floors of xôi — sticky rice, white or mung-bean, topped with braised pork belly, chicken, pâté, Chinese sausage and fried shallots. A Hanoi breakfast and post-midnight staple, open 06:00 until around 23:00.
Fried tofu, boiled pork belly, chả cốm and cold blocks of rice noodle on a banana leaf, all for dipping into whipped fermented shrimp paste sharpened with lime, sugar and chilli. Served from 09:00 to 21:00.
Half-day classes begin with a guided walk through Châu Long market, then hands-on bún chả over charcoal, nem rán and green papaya salad in an open kitchen. Lunch, drinks and printed recipes included; book a day ahead.
Unpasteurised draught beer brewed and delivered the same morning, poured into glasses on kerbside stools from about 16:00 until the street clears at midnight. Snack on nem chua rán, chân gà nướng and grilled squid.
