The menu begins with a salad of duck, fig and nectarine followed by Russian "pelmeni" dumplings made with Kamchatka crab and then a White Amur fish soup and a sorbet from sea buckthorn.

For the main course, the leaders have a choice of sturgeon with mushrooms and potatoes or an entrecote of marbled beef with grilled vegetables.

For dessert, they will be offered red bilberries from the taiga with pine nuts and condensed milk. White and red wines from the Divnomorskoe manor from southern Russia are offered.
