Napoli's in Utica makes a beautiful round roll. Call ahead. They have limited hours. If you ask far enough ahead, maybe they could bake on some caraway and rock salt for you. And while you're there get one of their tomato pies.
As for the beef, an easy cheat is to get some rare deli roast beef, whip up a pot of au jus, and soak the beef in it just long enough to warm it before serving.
