I absolutely loved the мароженое they sold in Soviet times. Delicious! Советское шампанское was another favorite. And as for food, well there was not a lot of variety when I was there because by then the economy was tanking... but there were still a few places where we went to eat and it was not all cockroaches and nastiness. There was a Georgian restaurant in Leningrad called "Tbilisi" which served some pretty good food. The commissary where we worked, on the other hand, that was nasty. But we got used to it. I learned not to look too closely at the cooks. Or at my plate. One time I found half a cockroach in my каша and I just pushed it aside and kept eating. That's when I knew I'd been there too long...
