This study examines the economic efficiency of monoproduct restaurant concepts in scaling ethnic cuisine businesses, focusing on how process standardization, menu concentration, and operational discipline shape revenue quality and cost stability. The research is motivated by the growing interest in scalable food-service models that preserve product authenticity while maintaining consistent service outcomes across locations. The purpose of the study is to identify the mechanisms through which monoproduct specialization influences operational performance and expansion potential in ethnic restaurant formats. The research design is analytical and comparative, combining a structured review of academic and industry sources with conceptual synthesis and framework-based interpretation of operational and economic indicators discussed in the literature. The study uses comparative analysis, systems analysis, process decomposition, and interpretive synthesis to evaluate links between product architecture, training intensity, production variance, service speed, customer perception, and scalability. The principal results show that monoproduct concepts tend to reduce production complexity, shorten staff onboarding, improve process repeatability, and strengthen brand recall, thereby supporting more predictable unit economics and replication logic during geographic expansion. The study concludes that the economic advantage of monoproduct concepts emerges not from menu limitation alone, but from disciplined standardization and alignment between culinary process design and service operations. The article's contribution lies in proposing an integrated analytical framework linking operational simplification to scaling economics in ethnic cuisine businesses. The study is limited by its non-experimental design and reliance on published evidence rather than primary field measurements. Practical implications include guidance for founders and operators designing scalable ethnic restaurant formats. Social implications relate to the sustainable market adaptation of culturally specific cuisines without loss of product identity.
