Business Center Favorites? Musts?

I'm going to NJ for a long weekend trip and it appears like there's a CBC right around the corner from our hotel. I'm insanely curious, love a good deal, and seriously contemplating a detour to take a look. (Insert Mr. Burns laugh here)

Before I drag the family - what should I be on the lookout for that isn't available at the regular warehouse? What's the 4-1-1 on Costco Biz?
