 CHAR: During the lunch scene Goodwin describes the Reuben Sandwich  as the only entirely invented sandwich entered in a sandwich contest  by Reuben Kay. Some claim that a wholesale grocer named Reuben  Kulakofsky created the sandwich at Omahas Blackstone Hotel back in  1925, but it was Fern Snider, a waitress at the Blackstone, that  entered the recipe in a national sandwich competition in 1956 and  won.
