Kilroy's has been a staple of Glen Rock for a long time, for a while being the only real supermarket in Glen Rock. Kilroy's has a great, although limited, selection of products. I personally like their fresh bread products a lot. Since the store is rather small, however, compared to the likes of a Shop Rite, I use this store only when I'm in a pinch. Prices here are also a bit more expensive than other places as it's a smaller store and more exclusive.
