Albeit, authentic, this cafe is VERY over priced.  A lot of truly lovely imports and tastes of the mother country.  The staff are very knowledgeable and have good recommendations of what to try.  I and a friend checked out this place due to the extensive reviews written up about it.  I have lived in neighbouring countries to Russia, in the former Soviet Union.  For two coffees, two small bowls of borscht, a slice of rye bread, and one can of kvas - the total was over \u00a315!  The cafe is rather cramped with only 2 tables, and not much room to stand.  If you go, check carefully what you are getting and ask about pricing in advance, or bring a hefty purse.
