Oh, man. When in Jersey, I go out of my way to find a deli/bodega/corner store with a few guys in there speaking a different language, the owner standing over a hot griddle, cutting up with those guys, ready to make me a bacon, egg, and cheese sandwich, salt and pepper, on a hard roll, just the right amount of tasty grease dripping off.
And, for lunch, the best pastrami and Swiss on rye that I've ever had was from a food truck in an industrial area in Newark. Same description as above, but the guys speaking a different language are standing around outside the truck.
