regionpolski 33 | 153 12 Oct 2009 #1I was saddened to learn that Boniek's Deli on Foster and Harlem has closed. They had very good food, especially the sledze in vinegar (not oil!!) swojska and czernina. Does anyone know where fresh czernina is still prepared? I checked the places on Archer Ave. and struck out. I bought the czernina for two friends who are up in years, and I would like to continue to make their day every once in awhile.
