The research aims to examine the process of developing new products in a fast-casual restaurant. Best of our knowledge this is the first research that reviewed the process of new product development in a fast-casual restaurant with empirical findings. In this context, a restaurant operating in Antalya has been identified as a research area, and the research has been conducted with the qualitative case study method. The data were collected in two different ways as participant observation and document review and were analyzed with content analysis. The new product development process takes place in seven stages as idea development, pre-screening, trial and error, prototype development, scale-up, scanning, finalization and application. The aspects of the process that are similar or different with different types of restaurants (fine dining, quick service restaurants) are discussed with prior research findings and suggestions are presented for future research.
