I will soon be forced to endure a cross-country flight home from JFK, and seek a substantial and delicious sandwich with which to amuse myself for the duration. I'm staying at Broadway and 75th--anyone have a recommendation for a particularly good sandwich shop in the area? It could be any sort of sandwich, but it needs to be tasty! Big's good, too--long trip. Took a look at the Manhattan board, but the best bets seemed to be in Brooklyn: do I really have to travel that far?
