Review: Com Dia - a sort of term that I think means set of the day is usually around 20-40K dong. you tell them the price you wish to pay and they will put on an equivalent amount of items. Typically you do not select what food you want on the plate, just leave it up to the kitchen to select for you. Anyhow, it is a simple but delicious and friendly place. I once took a group of some 10 Vietnamese to the second floor eating area, we had a feast for around 400,000 dong.
