My grandfather visited Moscow after chernobyl on invitation by some radiation chemistry prof he knew. You had to stand in line to buy a weight quantity of bread and other basic necessitys like cheese, butter oder meat. There was only one type of bread. They ate their eveninglunch in a park. I can not tell how the food was for official delegations but this was what a privat dinner with a relative well off friend looked like.
