Best Polish Bakeries in Chi and Best Sources For Kolachies
Oak Mill Bakery in Niles / (847) 318-6400
This is one of the very best Polish Bakeries. It's been around for years. Great stuff! Try the blueberry custard roll.
I find the Kolacky at the Oak Park Bakery excellent, but I'll be heading to Weber's to compare.
