As Jesse points out above, the festival website says it's cancelled. I based this event on the website, which I consider authoritative, so I guess it's a no-go. I hope they reschedule!
I just called these guys and they are doing a "scaled-back" program (no food) from 1-3pm. The food part will be at the reception, from 3:30-6 at the Polish Club, 3040 22nd St (at Shotwell).

Why does the homepage say Cancelled?
