"Big" might have described the 'stache of the original owner, decades ago; the storefront is small. As a consequence, however, all the volatile, mouth-watering aromas of a good sandwich shop have been confined, and intensified, when they greet you at the door.
If the proportions of the Bellybuster ($12.20) don't seem to match the hand-drawn artwork on the hanging sign out front, it's because you're looking only at the half I ate in-house; the other half was under wraps, keeping cool beside the soft drinks in the refrigerator case. The bread would be better if crustier, but the guts of the sandwich — ham, prosciuttini, cappicola, salami, mild cheese — were ample enough. Asking for "everything" added tomato, lettuce, onion, a wisp of oil-and-vinegar dressing, and a few shakes of seasoning that wouldn't be out of place at your favorite slice joint.
