This program was pretty entertaining, but not thorough, by a long shot.
Glaring omissions (that I'm aware of, but certainly there are more)
were any mention of the midwest's famous pork tenderloin sandwich,
along with Miami's Cuban sandwich.

They showed mostly sandwiches that have had a lot of press already -
lobster rolls, those Pennsylvania hoagies (can't remember of it's
Philly or Pittsburgh), Kentucky's "hot brown," the Philadelphia
(Cheese) Steak Sandwich, Chicago's Italian Beef, and a couple from
Louisiana, although I don't recall what they were at the moment.

They did show that thing with white bread, meat, French fries, and
coleslaw all in one. Didn't look real easy to eat.

They had a sampling of ethnic sandwiches - muffalata and falafel.

They might have included one or two from California....

I was really tickled that they did include Marshalltown's (Iowa) famous
Taylor's Maid-Rite sandwich shop that I've bragged on for years - they
even showed the basement where they cut up their own sides of beef
(they use it all, not just the "cheap" cuts - sirloin, ribeye,
everything), and said few people knew about it BUT, I'VE BEEN DOWN
THERE! LOL. My ex used to work there every holiday and school
vacation. It made me really hungry for some Maid-Rites from Taylor's.
