Butcher in Columbia, SC?
I'd second aginsky's recommendation of Caw Caw Creek. CCC usually have pork products for sale at the weekly All-Local Farmer's market, which is held most Saturday mornings at 701 Whaley Street. There is usually a beef guy and a poultry guy (Wilmore Farms) there, as well, and I bet you could order special cuts in advance. I've been to the Ole Timey Meat Market a few times. It appears to be a local butcher chain and is fine, if not particularly special. One place I'd like to draw to everyone's attention is The German Meat Market, located in a strip mall on Two Notch Rd. This is not a full service butcher, but the friendly proprietor makes a wide variety of his own German sausages and I believe smokes his own hams. Good stuff.
