Cha Ca La Vong serves only one dish—cha ca, a succulent fried-fish masterpiece, the recipe for which has been in the Doan family for generations (the name translates roughly to “curried Red River fish”).
After more than seven decades, cha ca became so entrenched in Hanoi that the city renamed the lane out front in its honor. A rickety flight of wooden stairs leads to the unremarkable second-floor dining room, full of equally rickety chairs. Patrons cook chunks of seasoned garoupa fish on a charcoal clay brazier, stirring in chives and dill. The rich, oily stew is then spooned into bowls of vermicelli rice noodles and enlivened by the addition of shrimp sauce, fried peanuts, and pickled vegetables. The secret ingredient, if you believe the rumors, is two drops of an essence extracted from the perfume gland of the ca cuong beetle.
