Effingham is where Interstate 57 and Interstate 70 meet. It is the seat of Effingham County, Illinois.
Since Effingham is the crossroads of two major Interstae highways there are plenty of truck stops, hotels, stores, and restaurants. The Pilot truck stop also functions as the Greyhound station. You can easily find your favorite fast food chain restaurant as well as some sit down chains. If you are in the mood for something local, I would suggest Niemerg's Steak House. They have great food at a reasonable price.
If you are in the mood for shopping, there is an outlet mall in Effingham.
