This study aimed to identify consumer demands and propose improvement measures for restaurants by conducting an importance-satisfaction analysis of the attributes that influence dining consumers’ restaurant selection. The key findings are as follows: An analysis of consumer hygiene behavior revealed that participants were particularly vigilant about washing food ingredients, checking expiration dates, and maintaining personal hygiene before meals. Notably, women exhibited significantly higher hygiene behaviors than men in 9 out of 12 items. The importance analysis of restaurant selection attributes indicated that “food cleanliness” and “food taste” were prioritized, with women assigning higher importance to almost all attributes, particularly emphasizing restaurant cleanliness and food taste. The satisfaction analysis showed that “food taste” and “food cleanliness” were the most satisfying attributes, with significant gender differences observed in 4 out of 26 items. The importance-satisfaction analysis demonstrated that satisfaction levels were consistently lower than importance levels across all 26 attributes. The ISA analysis identified that items in the second quadrant, such as restroom cleanliness, reasonable price, and the provision of food safety information, were in the most urgent need of improvement. Overall, the study highlights that consumers place a high level of importance on hygiene and cleanliness in restaurants, reflecting a market with increasingly stringent hygiene standards.

This study was conducted to provide basic data and insight into behaviors that result in increased continuous sales and competitiveness. This was done by examining the effect of personal involvement on customer satisfaction and trust, the effect of customer satisfaction on switching cost and loyalty, the effect of trust on switching cost and loyalty and by analyzing the indirect effect of trust and loyalty to personal involvement on switching cost and loyalty of the patrons of casual dining restaurants. In order to achieve the goals of the study, a hypothesis and structural equation were proposed based on preceding research and the proposed model was analyzed using LISREL 8.30 to prove the hypothesis and better understand the interactions between the cause and effect. The results were as follows: Six proposed hypothesis were chosen and the indirect effect was verified. In other words, customers' personal involvement was shown to have an effect on trust and devotion and satisfaction influenced switching cost and loyalty. Trust had an effect on switching cost and loyalty and by analyzing the indirect effect the customers' personal involvement was shown to affect the switching cost and loyalty through satisfaction and trust. The result of this analysis provides clues to better understand the eating-out behavior of customers and proves that personal involvement, satisfaction, trust, switching cost and loyalty are directly and indirectly related.

The purpose of this study is to investigate whether a group of predictor variables which constitute four determinants of dining satisfaction do exert a significant influence on messures of dining satisfaction in family restaurant.
