Abstract: The article examines the names of restaurants in St. Petersburg based on a linguocultural analysis. The subject of the study is the linguocultural codes of ergonyms in St. Petersburg. The object of the study is the ergonyms of St. Petersburg. The paper distinguishes the terms "linguocultural code" and "ergonym" to refer to the objects of research. An "ergonym" refers to a type of urbanonym that signifies the names of enterprises of various functional profiles. The term "linguocultural code" indicates the equality of linguistic and cultural components. The aim of the research is to identify specific linguocultural codes in the names of restaurants in St. Petersburg. The material for the study consisted of 700 names of restaurants and cafés in St. Petersburg collected from online resources. The aim of the article necessitated the comprehensive application of various methods: descriptive method, comparative analysis in the collection and analysis of ergonyms, synchronic method, classification method, method of linguocultural analysis, and quantitative counting technique. The scientific novelty of the research lies in the systematic identification of specific linguocultural codes in the names of restaurants in St. Petersburg. Moreover, to date, the number of scientific works dedicated to the analysis of linguocultural codes in the names of restaurants in St. Petersburg remains quite limited. As a result of the linguocultural analysis of the 700 names of restaurants in St. Petersburg, the dominant linguocultural codes were identified: anthropomorphic (27.5%), gastronomic (26%), and topomorphic (16.57%). The anthropomorphic code emphasizes the role of humans in nomination. It should be noted that the gastronomic code is characteristic of restaurant names. The study confirms that restaurant names serve as a "living archive" of the cultural memory of the city of St. Petersburg. Linguocultural codes function as semiotic markers and reflect the interaction of language, culture, and urban space.
