Roadtrip from Rockford to Bloomington, IL---any good eats along I-39?
India Bhavan in Bloomington shouldn't put you too far off course. We love their lunch buffet. They usually have dosas, pakoras, sambar, dal, chicken biryani, tandoori chicken, and several curries on the weekends. Usually, there are several vegetarian curries, as well as one or two with chicken or lamb. Their butter chicken and any eggplant curry are our favorites.
Have a good trip!
