An entire row of shops along Lý Tự Trọng Street sells the same dish: duck simmered in fermented tofu (chao). The broth is rich, carrying the distinctive salty tang of fermented tofu, with duck meat simmered until tender and falling apart, served with bok choy, fried dough sticks, or vermicelli. It's a warming, communal dish Cần Thơ locals often order when dining together. Because so many shops selling the same thing cluster along this one alley, locals simply started calling it 'Duck Alley' — walk in, and every household's kitchen sends out the same rich, fragrant aroma.
What is this dish, and how did Duck Alley come to be?
Vịt nấu chao (duck simmered in fermented tofu) is documented in the Vietnamese Wikipedia entry for 'Vịt nấu chao' as a signature southwestern dish. The Cần Thơ city government's official website (cantho.gov.vn) also includes a food column featuring the landmark 'Lý Tự Trọng duck alley.' An entire alley of shops selling the same dish has formed 'Duck Alley,' and this local consensus is fairly strong — it's not a claim from a single shop's own marketing.
Honestly, a promotional phrase commonly seen around here — something like 'selected among Vietnam's Top 100 specialty dishes' — turns out, on checking, to come from a selection process run by VietKings (Vietnam Records Organization), a private, joint-stock company, not a government body. Its credibility falls well short of an official or international rating — and it's worth noting the Michelin Guide still doesn't cover Cần Thơ either. This kind of title should be treated as a reference point only, not cited as an official certification. Thành Giao, one of the earliest shops in the alley, is among the oldest, but it's not the only or officially certified 'best' shop — several other shops in the same alley have been operating just as long, each with their own following.
How to eat it like a local
Notable shops and local knowledge
Thành Giao, the earliest shop to open in the alley, is a favorite for many, but the whole of 'Duck Alley' actually has several long-running shops competing side by side, each with slightly different broth intensity and tofu ratios — worth visiting a few to compare rather than settling on just one name.
Prices and Hours
- A pot of duck hot pot runs about 150,000–250,000 VND (roughly NT$183–305) depending on portion and number of diners — good for two or three people to share.
- Shops in the alley are mostly open for lunch and dinner, with dinner being the peak time for locals dining together — reserve ahead or avoid the rush.
- Try saying: 'Cho tôi một nồi vịt nấu chao.' (Give me a pot of duck simmered in fermented tofu.)
Things to Keep in Mind
- The 'selected among Vietnam's Top 100 specialty dishes' title comes from a selection by the private company VietKings, not a government or international body — take it as a reference, not gospel.
- Thành Giao is an old, established shop but not the officially certified 'best' — it's worth comparing a few shops in the alley to find the broth ratio you like most.
- The fermented tofu flavor in the broth is fairly strong; if you're not used to this style, ask the shop to adjust the saltiness or fermented intensity to taste.
The whole alley carries the same salty, fragrant aroma. Duck Alley doesn't rely on official certification — it relies on the pots each household has simmered for decades. Cần Thơ locals have already voted with their feet, and the answer is clear.
