Eating a po boy outside of New Orleans is like eating a crab cake outside of Maryland.
Not quite true. Not just for NOLA, though maybe that is the only place anyone here would go in that state. You can get great food (and REAL po boys), in Baton Rouge, any of the small swamp towns, my hometown, etc.
Louisiana is more than NOLA.
Same with muffulettas, jambalaya, gumbo, and the rest.
