The address of Shtetel, Inc, 660 Eastern Parkway, is a residential brownstone.
The KosherMeatStore sells fresh meat and poultry under several kosher supervisions: Lubavitch, Supreme (Rabbi Wiessmandl), OU and Debretzin. All but Debretzin were produced at Agriprocessors and continue to be produced at Agri Star, Agriprocessors' successor. Debretzin has a small but loyal customer base in Borough Park, Brooklyn.
Apparently, the KosherMeatStore.com doesn't sell Empire, Meal Mart or Abeles and Heymann – the major competitors of Agriprocessors, now Agri Star.
