For arguably the best Polish pierogi in town, you’ll need a membership to the Polish Library Building Association. But don’t worry: A one-day membership will only set you back one dollar. Once you’re official, you’ll have access to Grandpa’s Cafe and their handmade potato and cheese dumplings. Topped with caramelized onions and plenty of sour cream, they’re even better when washed down with an imported Polish brew. The cafe is only open Fridays and Sundays, so plan your visit accordingly.
