The market of a coffee shop has matured and competition among coffee shops has gotten fierce in Asia. In Korea, the number of take-out coffee shops has increased by 21.6% per year since Starbucks launched in 1999. Sustaining customer loyalty has been regarded as an effective strategy for the profitability enhancement of companies in the maturity stage. Since loyalty has been defined in both behavioral and attitudinal perspective, attitudinal loyalty was measured by repurchase intention of each brand and behavior loyalty was measured by repurchase behaviors (Olsen, 2002; Yi & La, 2004). This study aims to analyze both attitudinal and behavior loyalty of coffee shop and to establish effective strategies to improve customer loyalty
