This shop is very well known since the Soviet Union times.
They sell all kind of Armenian and georgian delicatessesn, although I went yesterday and did not find Georgina wines because they are, for the time being, forbidden.
I bought basturma, a sort of Armenian Jamon. They also sell cognac Ararat.
Apart from food and wines, they offer music, videos and DVD related with Armenia.
The old Christian chants from the XII century are a wonder. I have this tape at home.
The shop is located in the corner with Pushkin Square.
