I hope fellow chowhounds caught this delightful and delicious film. Here's a quote from the LPB website introducing the program: "Sebak and his crew traveled from Maine (lobster rolls) to New Orleans (po'boys and muffalettas) to San Jose (banh mi), talking to sandwich makers, sandwich eaters and sandwich lovers. The program is an explosion of American voices talking about tastes, traditions and toppings." I have already emailed LPB to request a rebroadcast.
PS - In New Orleans Sebak featured Domalisi's and Central Grocery.
