Snap! I just saw your post, Ghetto. You can drive to Center City Philadelphia in under 10 minutes from the Crown Plaza. There, you can check out South Street, Olde City or even Tony Luke's Cheesesteaks.
If you're all about stepping into some cocktails but don't want to venture across the river into Philly, just go across the street to Top Dog or take a cab to the Capital Grill at the Cherry Hill Mall. Cherry Hill was actually named after the first mall in America built under one roof. It used to be called Liberty County. (Or something close to that.)
