I've occasionally gone to a butcher out in Hightstown who closed a few years back and reopened recently. It wasn't exactly convenient (and their hours guaranteed I could almost never get there), but it was worth it for the quality.
Sadly, they are closed again.
Does anyone in the Trenton/Princeton area have any recommendations? I don't have any special requirements, nor are my needs that crazy - just random cuts of beef/pork that my local supermarkets never have available. (As a side note, the H-mart in Levittown, PA has a good selection of this stuff, but quantity is often an issue - if I need a 4 lb piece of pork belly, I'd end up getting multiple 1/2 lb pieces.)
