From memory, this is the layout of the local market at Hẻm 83 Hoà Hưng that I used to frequent on a daily basis in Saigon between 2000 – 2006. Stall holders have no doubt come and gone, dishes disappeared, maybe the entire market has upped and left. I'm planning to return in the coming months and will make a comparison map. I hope the Bún mắm is still there.
