A study of 63 Toronto restaurants found that certain attributes or amenities had a statistically significant effect on average check, as well as customers' ratings of decor and service quality. The features tested were offering catering, a dress code, late-night dining, live entertainment, outside seating, parking, smoking, take out, and some form of internet activity. Specifically, a dress code boosted check averages and improved ratings for decor, service, and food quality. Offering parking also boosted check averages. In contrast, offering takeout depressed check averages and reduced the ratings for decor. Offering a late-night menu had a significant negative effect on perceptions of food and service quality. The restaurant features offered most frequently were catering, takeout, and a smoking section.
