This does not mean that for each you need to cook a separate dish. Enough to ensure that they were not mixed products. For example, a beef dish, a dish of pork, a dish of vegetables. Such an abundance of dishes should be enough that everyone found something to their liking.
Portion for each
After you've compiled a guest list and said their tastes, you need to calculate wedding menu per person. The norm is about 600 grams of salads and cold appetizers, 1-2 servings of hot dishes, 1-2 servings of dessert and 1 cake. It is assumed that for 10 people, on average, 2 kg wedding cake. Here we find out that 70 people have ordered the cake from a weight of 14 kg.
Do not forget about alcoholic beverages. The more types of drinks will be presented, the better. Want about that for 10 people you need 3-4 bottles of spirits, 3-4 bottles of wine, and 2-3 bottles of champagne. To get the amount of alcohol 70, simply multiply the number of bottles of seven.
General guidelines in the preparation
But remember that appetites are different. So take it with reserve. It is much better after the Banquet to leave extra food than to see hungry guests. Moreover, the remaining food can be useful for the second day of the wedding.
As for the financial part, the average should start from the amount of 1500-2500 rubles per person depending on the products. But if you live in a small town, the amount can be significantly reduced.
Don't forget that many cafes and restaurants help your menu planning. For you to make a detailed description of what products and what quantities are necessary. Take into account all your wishes. Of course, if a few guests, the menu it is possible to make. But in the case of 70 people it is better to seek help at your cafe or restaurant. This option would be more economical and efficient.
