They do have a nice selection of quality Vodkas though. And nothing beats a bowl of Borsht, followed by Beef Stroganoff or Chicken Kiev and who would say no to a few scoops of caviar on a frosty winters morning, with a few shots of vodka to complement. There is Shashlik (Russian take on Kebab), and Solyanka soup, almost as good as Bloody Mary to cure hangovers. But apart from that, not much of tasty Russian cuisine.
I suppose over a hundred years of communistic rule, eating mostly potatoes didn't contribute much to culinary development.
