This article analyzes the role of street food in shaping Omsk urban identity and its potential for enhancing the city tourist appeal. The aim of the study is to comprehensively examine local residents’ perceptions of Omsk street food through the lens of its connection to regional traditions, identify contradictions in consumer behavior, and develop recommendations for transforming it into a tourist resource. Based on a large-scale online survey of Omsk residents (n=398), a comprehensive analysis of street food perceptions is conducted through the lens of its connection to local culture and history. The results demonstrate a significant contradiction between the high popularity and stable patterns of street food consumption among city residents and the weak association of street food with local culinary traditions. It has been established that consumer choice is determined primarily by taste, price, and convenience of location, rather than cultural significance. The authors introduce the concept of “latent gastronomic identity,” which explains the rootedness of street food in everyday practices in the absence of symbolic articulation. A four-stage model for transforming a gastronomic destination into a tourism brand element for Omsk is proposed. The conclusion substantiates the need for systematic efforts to integrate local identity into street food practices, promote regional gastronomic traditions, and develop event marketing. This will help overcome the “gastronomic amnesia” of the post-Soviet space and transform street food into a significant tourist attraction for Omsk, fostering economic and cultural development.
