It's a blini franchise, there used to be Teremok kiosks at just about every metro station in Moscow.

Cheap, hot, delicious, stuffed pancakes made to order and filled with whatever you wanted. I was on personal terms with the Teremok blini stand in our neighborhood we were there so often. America needs these.

Teremok is a Russian fast food chain that primarily specialises in traditional Russian dishes such as blini, pelmeni, kvass and borscht. Founded in 1998 by Mikhail Goncharov, their menu was adapted from the recipes of Goncharov's mother. Their restaurants operate in Moscow, Saint Petersburg, Ural, Southern Russia and Siberia. As of 2017 it has grown to 300 restaurants, which formerly included two in New York City that closed in 2018.
