Joe's Pork Store is in Astoria, on Ditmars Boulevard near 37th Street. It's been there since 1957, and is worth a visit. It's hard to find a place more authentic than this.
Joe's son Paulie, who currently runs the place, and makes all the delectable sausage, is a third-generation butcher. His grandfather had a shop in Harlem. The old cash register and butcher block from the Harlem shop can been seen inside. So can a meat chopping machine that Joe bought in 1957. It looks like new and has never been repaired.
It's a delight to visit this store. There's sawdust on the floor. The owner is happy to talk and seems to very much like what he does. He's not grumpy, as some butchers I've met can be. He'll give you tips on how to best to keep the flavor of the meat as your cook it. And the prices are very good.
