It is apparently the month for festivals!
Explore your Polish heritage at the Polish festival held Saturday and Sunday at the Polish Falcons Gardens (2013 St. Louis Avenue). There will be authentic Polish food and pastries as well as music and games. A Polka band will provide music Friday and Saturday night from 6:30-10:30pm (which means you're sure to see some great dancing!).
The festival is open for lunch on Friday from 11am-1pm and then dinner will be served from 4-7:30pm. Lunch/dinner will be served on Saturday from noon to 7pm. I don't have any information on the cost of the meals but I assume there is a charge for food.
