Cha ca La Vong is a unique specialty of Hanoi people, therefore one street in Hanoi was named as Cha Ca Street. 

Cha ca is made from mud-fish, snake-headed fish, but the best one is Hemibagrus (Ca lang). Fish bone is left away to keep fish meat only, then seasoning, clipping by pieces of bamboo, and frying by coal heat. An oven of coal heat is needed when serving to keep Cha ca always hot. Cha ca is served with roasted peanuts, dry pancakes, soft noodle soup, spice vegetables and shrimps paste with lemon and chilly.

The Cha ca La Vong Restaurant on No.14 Cha Ca Street is the "ancestor restaurant" of the dish.
