Looking for butcher shop in Mansfield/Columbus area
What about the Columbus flea market? Have you tried in there? I know there is a good fish store that some very picky relatives love. Quite frankly, there isn't much there (my sister lives not far from there in Lumberton). She hasn't found a good meat market and typically just goes to Wegmans when she wants meat. If your parents ever want to take a ride, right down 206 S into Hammonton, there is a great little old fashioned Italian grocery store called Bagliani's with an in-store butcher. I guarantee it's worth the ride down from Columbus. Excellent meats, roasts, Italian specialty items, deli, etc. They do different types of stuffed roasts and it's just a wonderful stop. Small, and very good service, especially in the meat dept.
If you search the board, someone on here mentions a meat market in Berlin, NJ, that they speak highly of. I also noticed a butcher on High Street in Burlington City, which would not be a bad ride for them. On 541 in Burlington Twp, not far from 295, I think there is also a butcher, though I know nothing about them either. Good luck and hopefully others may have some more suggestions for you.
