If you'll be driving along Roselle Road between Schaumburg and Inverness, you might be interested in the
St. Nectarios Greek Fest which is from June 22 - 24 this year. While they do offer a "drive thru" service for those who just want festival eats without leaving the comfort of a heated car seat, it tends to slow down traffic alone Roselle Road during festival hours, which run to midnight (FYI).
