Our daily existence is only possible through food, and ingestion of liquids, like water, without this partnership we could not survive long. If food is a necessity, sometimes practiced in the family, tasting homemade dishes and appetizing, other times we eat out, with many options in gastronomy. For those who work, lunch is a routine common to anyone, some take their food from home, the famous lunchbox, some have the privilege of having a cafeteria in their work environment, and others are obliged to seek, among many options, a good place to feed, satiating their hunger, but with limited time for it. The self-service, popular "restaurante a kilo", came in the mid-1980s, when there were very few options for those who needed to eat out, whether they were workers or passers-by, allowing consumers to choose from various options such as salads, pasta, paying only for the amount consumed, without getting stuck the traditional dish, which comes with defined ingredients. Due to the demands of the modern world, the novelty did not take long to spread throughout the country. Of course, this is an increasing trend, for, at the threshold of the third millennium, when time is the scarcest good, ready, varied, nutritious, well-made food served in a comfortable environment and at an affordable price is the that we all need. Generally a good self-service restaurant has a nutritionist to adjust to a healthier and balanced diet, enabling a tasty gastronomy, as nutritious and with advantages to the body and health. People are looking for a self-service restaurant because it offers quick, and somewhat economical, food, saving your time and money, and the person chooses what to eat, making it possible to set up your dish to your liking. There are many people who live alone in large centers, and prefer this type of comfort, looking for the best self-service to eat, with a very varied menu, which can offer several types of meat cuts, when offering barbecue, among others many options. Certainly the choice for a self-service restaurant, is a great alternative food.
