<![CDATA[The global coffee shop industry has evolved from a transactional, caffeine-centered trade to a multidimensional experiential market. However, the consumer behavior literature documenting this shift remains fragmented across marketing, hospitality, food science, and sustainability disciplines. To consolidate this fragmented landscape, this study conducts a systematic literature review following the PRISMA 2020 protocol, mapping the thematic, theoretical, and methodological frontiers of coffee consumer behavior research. A structured Scopus search covering 2015–2025, combined with multistage screening and a strict journal-quality threshold (SJR Q1–Q2), yielded a final corpus of 51 empirical studies. Thematic synthesis identified six distinct research streams: servicescape and interpersonal exchange, cognitive-sensory processing, identity and symbolic consumption, corporate social responsibility, omni-channel marketing, and disruptive technology. Methodologically, the synthesis reveals a heavy overreliance on cross-sectional survey designs analyzed via structural equation modelling (SEM), concentrated primarily in Asian markets. Crucially, this review exposes three persistent theoretical and empirical gaps requiring urgent scholarly attention: distinct satisfaction–loyalty decoupling in experiential contexts, a stubborn sustainability intention–action gap resistant to standard behavioral nudges, and an unresolved novelty effect regarding human–robot service interactions. This study contributes an integrated thematic map and advances a structured future research agenda emphasizing the need for behaviorally validated, longitudinal, and cross-cultural methodologies. The findings offer strategic and actionable insights for franchise and independent coffee shop operators navigating an increasingly saturated, digital, and value-driven market.]]>
