The super stop and shop in Westville sells kosher meat, which is nice, but if it's at all convenient, it's worth your while to stop at the Westville Kosher Meat Market instead. The prices are a little better, the variety is much greater (veal, bison, duck and other goodies instead of just beef or chicken), and the owner is a sweetheart. Introduce yourself once and she'll remember you forever. (And, if you're single, may possible try to set you up)
Also sells deli stuffs and Israeli imports, and can handle small catering projects.
Incidentally, if you don't keep kosher, consider buying kosher meat anyway. It's more expensive, but it guarantees humane slaughter, vegetarian diets, and better all around treatment of cows.
