I have found several websites each claiming to have a recipe for a "favorite" food of Tsar Nicholas II. These claims may or may not be true, but I thought it would be interesting to link to these sites so that those who are curious can recreate some of these dishes:
Russian Palace Vegetable BorschtDefinition: "Originally from Russia and Poland, borscht is a soup made with fresh beets. It can be prepared using an assortment of vegetables, or with meat and meat stock, or with a combination of both. Borscht can be served hot or cold; it should always be garnished with a dollop of sour cream." [Foodnetwork.com]
This particular recipe is actually from a former cook of Nicholas II:

[Foodnetwork.com]
This site says that this recipe was a favourite of the Tsar's:

A soup touted by this site to be a favorite of the Tsar's, as well as of a diverse group of characters including Ivan the Terrible, Lenin, and Stalin:

Said to be a favorite hors d'oevre of Nicholas II, named after his French chef. The chef survived the Revolution and became a successful restauranteur, where he re-named the salad "salade a la Russe" in honour of his former employer:
http://www.stratsplace.com/rogov/salade_russe.html Here are links to a couple of the foods that I found mentioned on the Alexander Palace's main site, for the Imperial luncheon served on "Tatiana's Birthday 1905." These may not necessarily be the exact recipes used for that occasion, but they are probably close in taste:
Botvinia (Cold green vegetable soup with fish)

http://www.recipesource.com/soups/soups/vegetable-soup1.htmlHere are some more foods that I read were mentioned in the family's diaries. Again, these may not necessarily be exactly like what the family ate, but they are probably very close, as they are traditional Russian dishes. Also, these recipes are just a starting point, and if they are not to one's liking, one can find variations in their style and complexity simply by searching for them on Google:
Blini (see definition above)http://www.foodtv.com/food/recipes/recipe/0,1977,FOOD_9936_26200,00.html
Pirozhki (small turnovers/dumplings, baked or fried)

It consists of a combination of sweetened pot cheese (or cottage cheese), nuts (usually almonds) and candied or dried fruit. Classically, this mixture is molded into the shape of a four-sided pyramid. The paskha is decorated with nuts or candy to form the letters XB, which stands for "Christ is risen." Paskha is the traditional accompaniment for the sweet yeast bread kulich." [Foodnetwork.com]
http://www.ruscuisine.com/cooking-recipes/index.php/breads-and-pastry/other/?recipe=204&offset=0A Kulich Definition: "A tall cylindrical Russian Easter cake that's traditionally served with pashka (a creamy cheese mold). Kulich is yeast-raised and flavored with raisins, candied fruit and saffron. It's usually crowned with a white confectioners' sugar icing, sprinkled with chopped candied fruits and almonds and sometimes embellished with a rose." [Foodnetwork.com]
