Though the Soviet Union no longer exists, various ethnic cuisines are still quite popular. Take, for example, Armenian food.
Food from the Caucasus region is also popular, even an Ossetian restaurant.
In St. Petersburg, Tatar-style “Chebureki” are ubiquitous.
Throughout St. Petersburg and Moscow, Georgian food is also hugely popular.
One may occasionally find food from farther afield, such as Kyrgyzstan.
