The big deal at the time of my visit was McDonald's was moving in to Moscow. Nobody ever talked about the fact that Baskin Robins was already there, way before the McDonalds store was built.
Apparently, they leave the 31 flavors part in the U.S.. We had the choice of Rum Raisin ice cream or Rum Raisin ice cream. We made the joke that it was 31 days between flavors. Since then, Rum Raisin has been my favorite flavor of ice cream.
The portion was about 2 ounces, about the same amount as we use for ketchup on our fries. It came in a little paper cup, with a 2 inch scoop in it. I think it was 1.3 rubles, but who knows now.
