As I will make a speech about Russian food and classical music this Satureday, I think that having some Russian food right after our productive English sessions would be a good idea.
There you can taste Russian signature dishes: Borsche, Shaslik, and Blini. Plus the most commom drink on streets during summer time in Russia: Kvac
I already booked a table for 12 at 6pm. It takes 5 mins walk to get there.
Let's have a Russian cuisine and chill out in such exotic vibes.
