Color photographic postcard showing the interior of the Rathaus-Café in Hamburg, specifically the "Riche-Bar" on the lower level (Tiefparterre). The bar features a long mahogany counter with shelving behind displaying glassware, a row of bar stools, ornate ceiling with recessed lighting, and a patterned tiled floor. Two upholstered armchairs flank a small round table in the foreground; a second seating area is visible at right. The card is described as Hamburg's largest entertainment venue of its genre.
