The research analyzes a large number of food facilities in Kyiv, Lviv, and Odesa. They are famous for special colorit, attractiveness, and innovation in stylistic and thematic solutions of their spaces. The stylistic analysis of the architecture of their interiors showed that there is mostly no trace of a single stylistic solution but a fusion of several styles or trends. 
 The main stylistic tendencies in the organization of food enterprises' object and spatial environment are defined: eclectic, fusion, a single modern style/direction, and auteur design without reference to any particular style. At the same time, within eclecticism, we distinguish the following vectors of its stylistic solution: displaying the atmosphere of different eras, the relevant historical styles of specific countries and places, and reproducing the interiors of food establishments from different periods and countries. Within the framework of fusion trends, we distinguish the following vectors: a combination of components of modern styles/trends with retro/vintage/antique interior items, with an authentic restored architectural, artistic details; use of contemporary style in combination with elements of historical styles: Art Deco, Classicism, Secession, etc.; the use of several modern styles/stylistic trends, a special mixture of components of many heterogeneous styles of the past and the present, has grotesque character and sometimes bordering on kitsch, also take place. Using a single dominant modern style or trend is the third tendency of style solutions for food enterprises' object and spatial environment. The fourth tendency is interiors, which do not have a clear manifestation of a particular style.
 The main styles and trends used today in the architecture of the interiors of catering facilities are identified, their definitions are clarified, and the scientific basis is developed. Modern stylistic trends, such as fusion, loft, industrial or industrial, shabby-chic, futuristic, steampunk, Provence, modern classics, and the Mediterranean, are reflected in the object-space environment of restaurants, bars and cafes. Eclecticism, minimalism, and high-tech are the most common styles in these spaces.
 Performed analysis allowed to determine the main approaches to interior architecture design of food establishments in the context of their conceptual and stylistic solution: conceptualism, eclecticism, environmental friendliness, symbolism, innovation, culturology and traditionalism, cohesion, harmonization, expressiveness, interactivity. Themes of artistic and figurative solution of the subject-spatial environment of food establishments were established.
