In a crowded sandwich-eating world of hoagies, grinders, subs, heroes, and po'boys, Norristown's own zep flies somewhat beneath the radar.
But in certain quarters, the intensely local, seven-decade meat-on-a-roll tradition is so closely associated with its birthplace to qualify as the Montgomery County version of Proust's madeleine.
"You take any Norristown kid from the '50s and you give him now, 50 years later, a zep," said Jerry Spinelli, 68, a children's book author and Norristown native, "and he will be transported back to his hometown."
The spicy, tangy zep is, Spinelli and the partisans argue, distinct from anything else that comes over a sandwich-shop counter, though the difference is admittedly subtle. And, as with the cheesesteak, there are disputed origins, two time-honored flagship shops, and separate camps arguing over the "real" vendor of choice.
