Mine was topped with pork mince, lettuce, tomato and a savoury mayonnaise. It was served with piping hot pancake and meat and contrasted by the cold rich mayonnaise. A delicious snack indeed.
Being extremely cold and in a Russian cafe, I also had their borcht, which was rich red riddled with beetroot slivers, minced beef and hearty meat-based stock.
The prices are cheap, the servings are large and the food is certainly winter satisfying.
