Research Background• Three important Criteria for Travelers
– Hotels– Restaurants– Shopping
• Travelers search restaurant reviews via internet:– Popular, famous places– Inexpensive places– Attributes: value, service, atmosphere, food, etc.
• Restaurant Managers’ Desire– Increase customer satisfaction– Increase customer loyalty; Keep coming back– Customers may be satisfied but may not return;
Need to understand this problem

OPRs & e-WOM
• OPRs (online product reviews)
– Consumers now rely on OPRs to help them to make a purchase decision.
– Products: Amazon.com, Epinions.com
– Food: Yelp.com, Zagat.com
– Travel: Tripadvisor.com, Expedia.com
– etc.
• e-WOM (electronic word-of-mouth)
– Online words disseminate faster than offline words
– Negative words diffuse faster than positive words

Our Research• Study 1: examines the different importance of each restaurant
attribute by overall travelers group using a conjoint analysis
• Study 2: examines differences in restaurant attribute importance by country-of-residence groups using a conjoint analysis
• Study 3: examines differences in restaurant attribute importance by different types of restaurants using a conjoint analysis
7/27
Study4: Studies 2 & 3 are combined!
I. Introduction
Prior Research on Restaurant Attributes
• Dube et al., 1994
• Koo et al., 1999– Most important attributes: taste of food, service, uniqueness, and price
• Tse, 2001– Female: importance difference smaller than that of male– The higher the education level, the greater the importance of price
• Not a single study that evaluates restaurant attributes by adopting a conjoint analysis using online secondary data!

II. Literature Review
11/27
Restaurant Attributes: Value• Value: net benefit gained after total costs incurred
– Net benefit could be greater or less depending on which attributes are more important to individual
– E.g., customers may feel price of restaurant is high, but feel like getting good value due to high food quality and nice atmosphere
– Customers compare one’s value with competitors’ value
– Price fairness is judged by:• Price of last transaction
• Most frequently occurring price point
• Market price in comparable transaction
(Bolton et al., 2003; Woodruff, 1997; Holbrook, 1994; Zeithaml, 1988)
II. Literature Review

Restaurant Attributes: Service• Service: restaurant service could be sub-categorized
into variety of attributes– Tangibles: customers’ detections of restaurant’s appearance,
cleanliness, comfortable seating area, attractive and legible menu
– Reliability: restaurant’s dependable operation (e.g., food is correctly served on time; mistake is corrected immediately)
– Responsiveness: staff’s attentiveness and expeditious action in serving customers
– Assurance: professional mannerism, knowledge of menu items
– Empathy: staff’s sensitivity and sincere caring of customers
(Landhari et al., 2008)

Research Design• Exploratory case study (Baxter & Jack, 2008)
• Subject of study: 3 famous restaurants serving great hamburgers in NYC, USA – Hamburger: quintessential food with mass appeal
• Crawled data on each restaurant review from TripAdvisor.com
• A conjoint analysis was used to calculate relative importance values of four attributes – Study 1: Overall
– Study 2: According to different groups of country-of-residence
– Study 3: According to different types of restaurant
– Study 4: Studies 2 & 3 are combined
III. Research Methodology
15/27
• Conjoint Analysis: relative importance of each attribute is determined (Green & Srinivasan, 1978).
• In our study, we adopted the same concept and applied to the traveler’ online ratings of restaurant attribute that reflect their staying experiences.

Developed Propositions (1/2)• Proposition 1: Travelers would place different importance on each of many
restaurant attributes.– Proposition 1a: Among four restaurant attributes, travelers would place the highest
importance on the food attribute.– Proposition 1b: Among four restaurant attributes, travelers would place the lowest
importance on the service attribute.
• Proposition 2: Both domestic and foreign travelers would place four restaurant attributes in a concurrent order of importance. – Proposition 2a: In examining only the service attribute, domestic travelers would convey
higher importance than foreign travelers.– Proposition 2b: In examining the atmosphere and food attributes, foreign travelers would
convey higher importance than domestic travelers.
• Proposition 3: Regardless of the restaurant types, travelers would place the utmost importance on the food attribute among all attributes.– Proposition 3a: In examining the value attribute among different price-ranged
restaurants, travelers would covey higher importance for the value in low-priced restaurants.
– Proposition 3b: In examining the service attribute among different set-up types of restaurants, travelers would convey higher importance for the service at a food stance.
– Proposition 3c: In examining the atmosphere attribute among different set-up types of restaurants, travelers would convey higher importance for the atmosphere in indoor restaurants.
V. Discussion and Propositions
23/27

V. Discussion and Propositions
Developed Propositions (2/2)
24/27
Research Contributions• Managerial Implications
– Restaurant management is able to evaluate importance of each attribute.– By comparing total importance with importance of each attribute,
restaurant management could efficiently allocate resources.– For general travelers, food attribute is more important than service
attribute.– Restaurant managers must realize foreign and domestic travelers
emphasize different attributes when dining.– “Food stance” type of restaurants must make sure to serve customers
expeditiously and professionally.
• Theoretical Implications– A conjoint analysis was used on voluntary data (restaurant customers
willingly expressing their opinions) for evaluation of 4 attributes (value, service, atmosphere, and food) of restaurants.
– Compared to survey questionnaire and scenario based experiments, OPRs better represent real thinking and intentions of customers.
– Unlike survey questionnaire which causes social desirability effect and CMB (common method bias), OPR data does not have to deal with this type of problem.
VI. Conclusion
25/27
Limitations & Future Research• Limitations
– Only 1 particular food (i.e., burger) data was collected for each of 3 types of restaurants.
– Subject restaurants are popular and famous.
– More positive than negative responses regarding attributes
– An exploratory approach (theory-building approach)
• Future Research– Number of restaurants should be increased.
– Include different locations of restaurants.
– Comparative study between well-operated and mismanaged restaurants
– Method triangulation: conjoint analysis (ratings) + content analysis (review itself)
– An empirical approach (theory-testing approach)
