Every fast food restaurant is now aware of the problem that every nation is currently facing. Indeed, we are observing a growing trend to consume healthy products, low in acid fats and cholesterol. Therefore, major fast food industries, such as McDonalds, Subway and Jack in the Box, are adhering to new international standards to gain a competitive advantage. Although fast food has not gone out of fashion, people still strive to buy a healthy breakfast, prepared quickly, due to the peculiarities of working life. At this point, all restaurants begin to pay attention to food quality, healthy diet and nutrition to deal with the problem of obesity and overweight. In order to understand the differences and similarities between the identified businesses, special attention should be paid to aspects such as food quality, service delivery and cost. Therefore, a quick glance at the restaurant policy reveals that all businesses pay attention to the healthy eating policy by promoting nutritional plans and taking care of customers' calorie intake. However, the difference lies in their pricing policies and service delivery. In all restaurants, the menu tab is full of diverse offerings that could satisfy all customer needs and preferences. In this regard, McDonalds constantly strives to expand the choice of dishes and products in terms of quality. For example, more and more menus and meals are specially designed for people who take care of their health and eat only low-calorie and nutritious breakfasts. In addition, there are also products intended for children and people allergic to certain products. McDonalds is considered the most popular type of topping and the middle of paper. The restaurant also takes care of people who are concerned about their calorie intake and, therefore, some of the dishes offered meet the requirements of a healthy diet. Jack in the Box lags behind the other two restaurants in terms of service due to the lack of certain features, like Wi-Fi zones, lack of servers, and huge lines. However, this is compensated by high quality food and drinks. Since the restaurant adheres to an innovative growth strategy, its pricing strategies are also sophisticated. Despite the emphasis on effective marketing and promotion, the pricing strategy remains traditional. The task of managers is to trace competitive prices and adjust them to the current market environment to maintain a competitive advantage. Overall, the pricing strategy is not much different from other restaurants..
