They get the extra star for the quirky fun staff, but the food is meh. Best for a beer and appetizer, I wouldn't go here for a full on Polish meal. It really does have a dive bar atmosphere, and they have a little outdoor section with one of those heater things for the colder months.
I don't really understand why this place gets such high ratings though, I certainly didn't find anything outstanding about the place other than the friendly staff.
