I've been to Bernat's several times. The store is small, but the prices and the quality are worth it. Their Kielbasa and deli hams are the best you will find anywhere. I can't say enough good things about the quality of their food.
Most of the workers speak polish with some broken English, but you can manage. All of the products, except for a handful, are direct from Poland and have no English on the label. I have managed however to have the staff help me decipher what the packaging says. I've never once been disappointed with what I have gotten from there. I love to go - its the only place I will buy some of my deli meats!
