It would not be an exaggeration, to say that each of us at least once in his life came across awful service in restaurants. It usually happens, that you  waste time, trying to imagine the taste of the meal with an  exotic name; you know how is it to have on your plate something that you don`t like, or in displeasing amount. In case you are pressed for time and money, but really hungry a buffet will save you from starving!
Instead of snobbery and official atmosphere of expensive restaurants, here everything is democratic. So, a buffet is a meal-serving system where people serve themselves.
That is why such buffets  are popular among people of any age and income. They also  give customers a great deal of choice and the ability to inspect food thoroughly and  closely before selecting it, in case to avoid dissatisfaction.
The modern buffet was developed in France in  the 18th century, soon spreading all over Europe. Originally the term referred to the sideboard where the food was served, but eventually became applied to the form. The buffet became popular in the English-speaking world in the second half of the nineteenth century.
The history of  Vegas buffets in the United States of  America is closely connected with Herb McDonald and the city of  Las Vegas. The thing is that  the prominent casino publicist introdused the idea in 1946 at the El Rancho, starting the development of the Vegas buffets. Usually they  belonged to the casinos and  opened  each midnight. It was one more draw for the casino-players, and what a draw! For the price of 1.50$ only , you could taste shrimp and lobster, hors d'oeuvres, relish, salads, and sauces; crab, herring oyster, sturgeon, octopus, and salmon; turkey, ham, roast beef, casseroles, fondues, and curries; cheeses, fruits and pastries. Moreover, you could repeat the procedure of  collecting food on your plate as many times as you wished , and it depended on your capacity only!
Of course, it might have been a terrible injustice to conceal such treasures as Vegas  buffets from other people. So, soon the city was filled with these restaurants. Small and big, modern and old-fashioned, Vegas buffets enjoy great popularity.
