This study aims to thoroughly examine the influence of menu variety, taste, and price on customers' purchasing decisions at CEZ-ROS Restaurant, located in Kediri Regency. Understanding these factors is crucial for the restaurant to enhance customer satisfaction and improve sales performance. The research employs a quantitative approach with an associative research type, designed to explore relationships between variables. The sampling technique used is accidental sampling, where respondents were selected based on convenience and their availability during the data collection period. This method allows for practical and efficient data gathering from actual restaurant customers. Data analysis involves several statistical tests to ensure accuracy and reliability. Initially, validity and reliability tests were conducted to confirm the suitability of the questionnaire. Then, multiple linear regression analysis was used to determine how menu variety, taste, and price individually and collectively influence purchasing decisions. Additionally, t-tests assessed the significance of each independent variable, while the F-test evaluated their simultaneous effect. The coefficient of determination (R²) provided insight into how much variation in purchasing decisions could be explained by these variables. The results indicate that menu variety, taste, and price significantly impact purchasing decisions both individually and together. Specifically, customers prefer restaurants offering a diverse menu, delicious food, and reasonable pricing. The F-test confirms the strong combined effect of these factors on consumer behavior. However, the coefficient of determination also suggests that while these variables are important, other external influences such as service quality, ambiance, and promotions may also affect purchasing decisions. Overall, this study highlights that CEZ-ROS Restaurant should focus on maintaining menu diversity, enhancing taste quality, and setting competitive prices to attract and retain customers effectively.

This study aims to determine the influence of independent variables, namely Promotion, Location, and Product Variation, on the dependent variable, Purchase Decision, at Seduhlur Coffee Kediri. The research method used is quantitative, employing multiple linear regression analysis with the assistance of SPSS version 26 software. The sampling technique applied in this study is incidental sampling, which involves selecting respondents who happen to be present and meet certain criteria at the time the research is conducted. Based on the results of data analysis, it can be concluded that the Promotion variable has a positive and significant partial effect on Purchase Decision. This indicates that the better the promotional strategies carried out, the more likely consumers are to make a purchase. Similarly, the Location variable also shows a positive and significant partial influence, suggesting that the comfort and accessibility of Seduhlur Coffee’s location play an important role in influencing consumer decisions. Product Variation is also found to have a positive and significant partial effect on Purchase Decision, meaning that a greater variety of products offered increases the likelihood of attracting consumer interest.

This study aims to analyze the influence of brand image, product variety, and bundling price on purchasing decisions among X consumers. The method used is a quantitative approach with a causal research design, so as to be able to explain the cause-and-effect relationship between variables. The research data was obtained by distributing questionnaires to 96 respondents who are active consumers of X. To ensure data quality, a series of tests were conducted including validity, reliability, normality, linearity, multicollinearity, and heteroscedasticity. The main analysis used multiple linear regression supported by t-tests, F-tests, and coefficient of determination (R²) processed using SPSS software version 26. The results showed that brand image had a significant effect on purchasing decisions, indicating that consumers' positive perceptions of X's reputation were able to encourage higher purchasing interest. Bundling price also proved to have a significant effect, because the strategy of combining package prices was considered to provide economic benefits and added value for consumers. In contrast, product variety did not have a significant effect, indicating that consumers place more emphasis on brand image and pricing strategies than simply menu diversity. However, when tested simultaneously, all three variables were still shown to have a significant influence on purchasing decisions. The coefficient of determination value of 0.594 indicates that the combination of the three variables can explain 59.4% of the variation in purchasing decisions, while the remaining 40.6% is influenced by other external factors such as service quality, consumer trends, promotions, and customer experience. These findings reinforce the understanding that a strong brand image-based marketing strategy and the implementation of appropriate bundling prices can be key to increasing consumer appeal. For local coffee businesses like X, this study provides practical implications to focus more efforts on strengthening brand image, creating a consistent consumer experience, and optimizing pricing strategies.

This study investigates the influence of promotion, brand image, and location on purchasing decisions at 3Second Store Kediri. The research employs a quantitative approach using both primary and secondary data sources. The primary data were obtained through the distribution of questionnaires to 309 respondents, while the secondary data were collected via interviews with store supervisors and direct observation at the research site. The variables under examination include promotion, brand image, and location as independent variables, and purchasing decision as the dependent variable. Data analysis involved both partial and simultaneous hypothesis testing to determine the strength and significance of each variable’s effect. The findings reveal that, partially, each of the three independent variables—promotion, brand image, and location—has a significant and positive effect on purchasing decisions. This indicates that improvement in any of these aspects will lead to a higher likelihood of customers making a purchase. Simultaneous testing also demonstrates that the three variables collectively exert a significant and positive influence on purchasing decisions. Among these, promotion emerges as the most dominant factor affecting purchasing decisions, as confirmed through the partial t-test results. The coefficient of determination (R²) is 0.581, which signifies that 58% of the variation in purchasing decisions can be explained by the three examined variables, while the remaining 42% is attributed to other factors not covered in this study, such as product quality, customer service, and pricing strategies. These results suggest that marketing strategies focusing on well-planned promotional activities, maintaining a strong and positive brand image, and choosing a strategic store location can effectively increase customer purchasing decisions. The findings provide valuable insights for retail management, particularly for fashion retail brands like 3Second Store, in developing targeted strategies to optimize sales performance.
