Food service or catering industry defines this business as, institutions, and companies responsible for any meal prepared outside the home . This industry includes restaurants, school and hospital cafeterias, hotels, catering operations and many other formats. Because food is a basic necessity of life and the increasing hectic lifestyle of people, food service industries enjoy a lot of customers all over the world .
According to the National Association, a growing trend is global cuisine with 66% of customers eating more widely in 2015, than in 2010. The companies that supply food service operators are called food services distributors. Food service distributors sell goods like small wares (kitchen utensils) and foods served in restaurant according to . This industry is divided into two groups. Those that prepare and serve food and those that produce and distribute food equipment and services are needed by food providers . The food service industry has become one of the most profitable industries in the world . There is a lot of competition in the food service industry, so for such business to survive and grow, the service quality must be high and the customer satisfaction must be achieved .
Nutrition is the process of providing or obtaining the food necessary for health and growth. It is the process of taking in nutrients from the food you eat. These are needed for energy, maintenance of tissue and regulation of body processes: carbohydrates, fats, protein water, vitamins and minerals  . For food to be nutritious, it has to meet same conditions which include the way the food is prepared and the way it is stored . The diet of an individual is what he eats, which is largely determined by the availability, the processing and palatability of foods. A healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leasing, and that reduce risk of food borne illnesses. On the other hand, when a diet is poor, it has a negative effect on people; some researchers have these to say . A poor diet may have an injurious impact on health, causing deficiency diseases such as blindness, anemia, scurvy, premature birth, still and cretinism . Improper nutritional intake can also lead to health threatening conditions like obesity metabolic syndrome  and chronic’s diseases like cardiovascular disease, diabetes and osteoporosis . A poor diet can cause the wasting of kwashiorkor in acute causes, and the stunting of miasmas in chronic cases of malnutrition . Because food is a basic need of life and because of the hectic lifestyle of people, many choose to visit a restaurant.
Healthy Diet: Nutrition guidelines recommend a whole plant food diet, and recommends using protein only as a condiment with meals. A National Geographic cover article from November 2005 entitled, The Secrets of Living Longer, also recommends a whole plant food diet. The article is a lifestyle survey of three populations, Sardinians Okinawa’s, and Adventists, who generally display longevity and “suffer a fraction of the disease that commonly kill people in other parts of the developed world, and enjoy more healthy years of life” . In summary, they offer three sets of best practices to emulate, which include eating fruits, vegetables, and whole grains. Nutrients are substances that provide energy for activity, growth, repair of body tissues and keeping the immune system healthy . We have six nutrients in food: Protein, Carbohydrates, fats and oil, Vitamins, minerals and Water. These nutrients can be classified into two according to how they work in the body. Macronutrients: carbohydrates, protein, Fats and Oil and Micronutrients (Small Nutrients): Mineral salt and Vitamins. Water is general to all the nutrients and aids digestion of food responsible for sweat, tears and urine . The above are basic nutrients required for good health. When anyone is lacking in these the body would not function well .
Nutrients are components in foods that an organism uses to survive and grow. Macronutrients provide the bulk energy an organism’s metabolic system needs to function while micro nutrients provide the necessary cofactors for metabolism to be carried out. Both types of nutrients can be acquired from the environment, .
Micronutrients are used to build and repair tissues and to regulate body processes while macronutrients are converted to, and used for, energy . The importance of eating the right nutrients cannot be overemphasized. For people to be healthy and function well we have to eat fresh whole foods with the right nutrients . This is also supported by the George Mateljan Foundation which says, “The benefit of deriving nutrients from eating fresh whole foods which provide not only an abundance of individual’s nutrients but also the variety necessary for their optimal function”. For example, amino acids, biotin, calcium, chlorine, chromium, copper, fiber, flavonoids, folate, iodine, iron, magnesium, manganese, molybdenum, omega 3-fatty acids, pantothenic acid, phosphorus, potassium, carbohydrates, selenium, vitamin A, vitamin B1 (Thiamin), vitamin B12 (Cobalamin), vitamin B2 (Riboflavin), vitamin B3 (Niacin), vitamin B6 (Pyridoxine), vitamin E, vitamin D, vitamin K, vitamin C and Zinc have different functions in the body .

It was observed from this research study that the standard of Chicken Republic and Mega Chicken restaurants determines the extent of the quality of food. Mega Chicken restaurant seems to have more customers than Chicken Republic. It also seems that the costumers of Mega Chicken have more satisfaction than those of Chicken Republic .
There is a relationship between food quality and customers patronage. Therefore if a customer is not satisfied with the level of service in a restaurant, the customer may not patronize that restaurant again whereas a customer who is satisfied with the level of service provided by a restaurant will keep patronizing such restaurant and even bring more customers .
In addition, the quality of service provided by a restaurant determines the extent to which customers will patronize them. Restaurants customers especially in a developed environment have interests in the way they are being received by such restaurants. Customers are interested in the response of their request, the mode of operation, the kind of chairs they sit on, the neatness of the staff and the welcoming method of the staff .
Also the food quality is a determinant of the level of customer patronage in a restaurant. The taste of the food, the aroma of the food and nutritional value of the food are highly considered by the customers from the research, it could also be observed that the customer are very passionate about the price and the value of the food bought in a restaurant. Where the price and the value are correlating, customers tend to patronize such restaurant again and again. Meanwhile if the price and the value enjoyed by customers are different, the customers will switch to other restaurants where they will enjoy the value for their money  .
The research also shows that the customers are indifferent to the kind of healthy food they consume. In the research, it reveals that a restaurant that sells unhealthy food will lose most of their customers. The customers want to eat healthy food always  .
This study assessed the organoleptic features and services of Chicken Republic restaurant in comparism to organoleptic features and services of Mega Chicken restaurant in Nigeria.
Five (5) research questions were raised as variables which determine the level of patronage of the said restaurants. The variables are customer’s satisfaction, quality of services, quality of food, price and value, and health food. The study further investigated how these factors affect the level of patronage of restaurants in Nigeria. To accomplish this, a questionnaire was printed, verified and distrusted to the customers in both Chicken Republic and Mega Chicken republic and Mega Chicken. Two hundred (200) copies of the questionnaire were given to Chicken Republic customers while one hundred (100) copies were given to Mega Chicken Restaurant in Lagos. The researcher used simple random sampling in order not to be bias in choosing the population for the study. The questions were collected and presented in a table using simple percentage method of analysis. The study shows that the customers preferred Mega Chicken Republic.
· The results also show that there is a relationship between customers’ satisfaction and customer patronage in the choice of restaurant.
· The quality of food has influence on the customers’ patronage in a restaurant.
· The respondents agreed that the quality of services determines the customer patronage in a restaurant.
· The study reveals that healthy food has a great influence on the customers’ patronage of a restaurant.
Based on the findings of this study, the following recommendations are made:
· Nigeria restaurants should improve on the variables tested in this research work.
· Customer’s satisfaction should be given a priority. Quality customer services or customer delight services should be improved upon.
· Also, in order to have more customers, Nigerian restaurants should consider the value and the price, before tagging a certain price to their goods.
· The quality of food should also be improved upon, because the customers are now aware of negative effects of poor food quality on their health.
· Potential restaurant owner should consider the environmental condition of the place they tend to situate their restaurants. This is because, the result of the survey shows that customers consider the environment before they enter into any restaurant.
· Lastly, restaurant owners should endeavor to organize seminar, check spelling and workshop for their staff in order to keep abreast of improved methods of rendering customer delight services.
Suggestion for Further Studies
The study should be repeated taking other restaurants as case studies. Also other variables, such as customer’s income, and market structures as factors that determine customer patronage should be taken into account.
