I’ve been spending most of this week following around Xanth Clay, a food writer for The Daily Telegraph, and the two owners of Pho Restaurants in London on a multi-day eating extravaganza, from local market stalls and well-known street-side noodle joints to posher cooking classes and more upscale eateries in Hanoi. The above image is an outtake from one of the many market trips we’ve so far made. It’s not the kind of thing that many publications will run, but it’s what I think of when I think of wet markets in the capital. A crowded fish tank, water-splashed concrete and fishing boots. Sometimes purple.
