I bought Soviet champagne, not expensive, 2 bottles, both without gas, a complete disappointment . It's not about money, it's uncomfortable in front of people. The last time this happened was in the 90s, it was a shame.
The only thing that makes me go there more or less is Sveta's canteen. And that Uzbek girl at the cash register is very harmful. And make a non-cash payment. They've already got it with their cash.
