FYI, I saw in the Gazette today that the former butcher from Jim's opened his own place in La Grange Park. I don't know if anyone posted on this previously but here is the address:
Morini's Meat Market & Deli
1101 E. 31st St.
The ad also says that they are using the same great recipes and spices from Jim's. I never had the chance to try Jim's so I'll make a point to try Morini's.
