# Introduction angladesh has a remarkable track record for growth and development, aiming to be a middle income country by hers 50th anniversary (World Bank 2021). With the increasing level of development, people are more engaged in economic activities. By the expansion of business and employment opportunities people also have engaged in outside activities. Food is the basic need of social beings; people have to take food thrice a day. As people work outside of their homes, they have to eat at hotels and restaurants. Sometimes people go with their family, peer, and friends to take food at an outside restaurant. Businessman fixes their important meetings at the restaurant. Now a day's different social and cultural programs like birthday parties, marriage ceremonies, and inauguration ceremonies are held at hotels and restaurants. That's why the restaurants service industry has become very popular. The growth of restaurant industry is increasing higher year after year, according to BBS (2018), the restaurant industry earns Tk68.2 billion. But in 2019, this industry, earns Tk73.16 billion. Despite the growth of the to external and internal factors in its business environment. The external factors include the highly competitive market, and internal factors include the restaurant environment, staff and employee behaviors, waiter service, restaurant special facilities and so on (Harun et al. 2013). Sometimes the customer visit with their family, friends and peer. At this time they desire best service from the restaurant (Younus et al. 2015). Restaurant environment is the most important factor to a customer. Customer demands a calm and noise-free environment where they can enjoy the food and Bonaparte. The environment should provide privacy to the customer (Haghighi and Dorosti, 2012). Arrangement of menu variety and food chart helps customer easily select their food. Procedure of wide range of menu items supports customer to choose their favorite food before eating at the restaurant, the food delivery time is also an important issue. Sometimes customers lost patience when they get late food delivery (Harun et al. 2013). Tamanna (2016) found that menu price, service quality and restaurant atmosphere are important factors for young customers to choosing the fast food at the restaurants. Restaurant entrepreneurs should consider the factors such as quality and price of food, to development of the restaurant (Latif et al. 2015). The selection of a restaurant is also dependent on quick service, physical atmosphere, food superiority and pricing (Tabassum and Rahman, 2012). Studies show that the consumers give most importance to the brand reputation of the food item charted by nearness to receive and availability, similarity of savor with earlier experience, cost and quality of the food, rebate and taste, sanitation and hygiene, salesmanship and decoration, fat and lipid level, and self-service factors (Islam and Ullah, 2010). According to Choi and Zhoa (2010), they revealed that the reasons for choosing a restaurant with concern health issues, yearly income level, the financial plan for dining out, and weight concerns. Cleanliness, food quality, and friendliness of the staff are most important factors for selecting the restaurant of travellers (Tripp et al. 1995). The study found that the physical design and exterior of the restaurant did not have a significant effect for choosing a restaurant (Andaleeb and Conway 2006). Restaurant location is also important factor for selecting the restaurant. (Edwards et al. 2003) restaurant industry it is facing numerous challenges due privacy, the brand name of the restaurant, and availability of ready-made food is influencing factor for choosing a restaurant. There have several studies on the factor affecting customer decisions for choosing a restaurant. Most of the studies conducted with 3 or 4 variables in different cities. But no study has been done in Khulna city. So this need inspired me to conduct this study on Khulna city to explore how customers consider different factors before dining at the restaurant. In this study, we determine the factors as well as the correlation between two or more factor and their significance. # II. # Materials and Methods This study has collected primary data from 100customers who frequently eat in the restaurant at Khulna city.

Car parking facilities means the customers prefer the restaurant most where they park their car, bike, etc. # Menu Variety: It means the restaurant's capability to arrange different types of food for different types of customers such as, some people like Chinese food, some like Bangladeshi food, and some like Indian food. To attract the more customers, a restaurant has to arrange every type of dish. # Special Facilities (Vegetarians and non-vegetarians food, low price, Children's playground): It describes the restaurant can manage vegetarian and nonvegetarian customer segments and children's playground. In special cases, the customer often prefers the restaurants most where their children can play and fun. # Waiter Service: Waiter service means when a waiter serves any type of service, how quickly they serve and their manner. # Other Employee Service: The customer did receive any service from the restaurant's front desk executive, security guard, and receptionist. 7.

They dined at this restaurant before or it is the new one. # 9. Fast Order Delivery: How many minute's a customer waited after giving an order for food. More than the customer's expected time or shorter than the expected time. # a) Analysis of correlation H 1 = There is positive relation between fast seat arrangement and a restaurant environment of Khulna City. Table I shows the value of the relationship between fast seat arrangement and restaurant environment is .625, and the significance value is .000. Thus the hypothesis is accepted. There is a positive and strong relationship exists between fast seat arrangement and the restaurant environment of Khulna city. H 2 = There is a positive relationship between menu variety and special facilities of the restaurant of Khulna City. From table II correlation coefficient between menu variety and special facilities is .527 and the significance value is .000 which shows there is a positive relationship between menu variety and special facilities of Khulna city. Table III shows the correlation coefficient between special facilities and waiter service is .290, which shows a moderate relationship between special facilities, and waiter service and the value .063 shows the relationship is insignificant. The above table (Table IV) shows the correlation coefficient between supervisory staff help and repeat purchase behavior of the customer is .117 which, shows there is a moderate relationship between these two variables and the relationship is insignificant. # b) Regression analysis The purpose of the regression analysis measures the relative influence of each independent variable on the dependent variable. The Pearson's correlation value, R = 0.672> 0.50 which means there was highly correlation between the variables and the R square was 0.451 (Table V) which, denotes that about 45% variation of the dependent variable was explained by the independent variables included in this model. of freedom which is also less than the calculated value of 2.926, means the null hypothesis is rejected at 1% significance level. It also means that there is a significant correlation between the studied dependent variable and independent variables. It means that there is a relationship between the dependent and independent variables under study. So, we can say that the variables under study are very coherent. The study considers the following factors where the customer decision for choosing a restaurant at Khulna city. It was hypothesized that there is no relation between the independent variable (quick seat arrangement, fast order delivery, known restaurant, waiter service, other employee service, menu variety, restaurant environment, special facilities supervisory staff's help) and dependent variable (choosing restaurant).To test the hypotheses, multiple regression analysis was used. Looking at the unique individual contributions of the predictor, the result (Table VII # Hypothesis # Conclusion From the above results and discussion, it has been concluded that the restaurant industry has become very competitive. To sustain in this competitive marketplace every restaurant company should put more effort into customer retention. In this competitive era, to become a market leader, not only food quality is important, but also restaurant's other features and services are very much important. The finding of the study also reveals that there is a strong relationship between customer visits and restaurant service. When a customer experiences good service from a restaurant, they will share with other people about good services. By providing the best service and considering the factor, it will help every restaurant company to capture more market share. Thus the findings of this study will help the restaurants to identify the ways to retain existing and loyal customers and attract new ones.
