Although it is not actually referenced in the movie, we can assume that Rocky and Adrian opened the Italian restaurant together – guess that proves that Adrian’s spaghetti really was good! Adrian’s Restaurant, according to its signage and menu, was established in 1995. In Balboa, we see Rocky himself shopping for the restaurant’s fresh food at Philly’s Italian Market, the same place where he used to take his morning jog in Rocky and Rocky II. 
Owner Greg DiStefano has put together a fascinating read about how Victor Cafe was chosen by the Rocky Balboa production to appear in the film back in 2005. DiStefano explains that Sylvester Stallone liked the vibe of his restaurant so much that the production decided to incorporate more of the Cafe’s music and opera decor into Rocky’s fictional restaurant than was originally planned.
