Here is a location that required absolutely no work to find.
In Rocky Balboa, Rocky owns a restaurant called Adrian's. The real place is the Victor Cafe in Philadelphia.
I got to visit it before Christmas last year and I had a great time. I even got to sit in the same seat as Spider Rico:
The food was great and my waiter sung opera. Really. As I am eating a plate of shrimp my waiter rings a bell and starts belting one out.
Victor Cafe is located at: 1303 Dickinson St, Philadelphia, Pennsylvania 19147
